Read  this firstBe sure  to follow the important tips given here  to get the most  use  and  enjoyment out of your computer. Failure to do so might lead to discomfort or injury, or cause your computer to fail.Protect yourself from the heat  that your computer generates.When your computer is turned on or the battery is charging, the base, the palm rest,  and  some other  parts may become hot.  The temperature they reach depends on the amount of system activity and the level of charge in the battery.Extended contact with your body,  even  through clothing,  could  cause discomfort or even  a skin burn.  Avoid keeping your hands, your lap, or any other  part  of your body  in contact with a hot section of the computer for any extended time.  Periodically  take  hands from using  the keyboard by lifting your hands from the palm  rest.Protect yourself from the heat  generated by the ac power adapter.When the ac power  adapter is connected to an electrical  outlet  and  your computer, it generates heat.Extended contact with your body,  even  through clothing,  may cause a skin burn.  Do not place  the ac power  adapter in contact with any part  of your body while it is in use.  Never use  it to warm your body.Prevent your computer from getting wet.To avoid spills and  the danger of electrical  shock, keep  liquids away from your computer.Protect the cables from being  damaged.Applying strong force to cables may damage or break  them.Route  communication lines, or the cables of an ac power  adapter, a mouse, a keyboard, a printer, or any other electronic device, so that they cannot be walked on, tripped over, pinched by your computer or other  objects, or in any way subjected to treatment that could  interfere  with the operation of your computer.
 
Protect your computer and data  when  moving it.Before  moving  a computer equipped with a hard  disk drive, do one  of the following, and  make  sure  that the power  button is off or is blinking:  Turn it off.  Put it in sleep mode.  Put it in hibernation mode.This will help to prevent damage to the computer, and  possible loss  of data.
 
Handle  your computer gently. Carry your computer carefully. 
Do not drop,  bump, scratch, twist, hit, vibrate,  push, or place  heavy  objects on your computer, display,  or external  devices.
 
  Use a quality carrying  case that provides adequate cushioning and  protection.  Do not pack  your computer in a tightly packed suitcase or bag.  Before  putting  your computer in a carrying  case, make  sure  that it is off, in sleep mode, or in hibernation mode. Do not put a computer in a carrying  case while it is turned on.Important  safety informationNote:  Read  the important safety  information  first.This information  can  help you safely use  your notebook computer. Follow and  retain all information  included with your computer. The information  in this document does not alter the terms  of your purchase agreement or the Lenovo Limited Warranty.  For more  information,  see  Warranty Information in the Safety,  Warranty, and  Setup Guide  that  comes with your computer.Customer safety  is important. Our products are developed to be safe  and  effective.  However,  personal computers are electronic devices. Power  cords, power  adapters, and  other  features can  create potential safety  risks that  can  result  in physical  injury or property damage, especially if misused. To reduce these risks, follow the instructions included with your product, observe all warnings on the product and  in the operating instructions, and  review the information  included in this document carefully.  By carefully following the information  contained in this document and  provided with your product, you can  help protect yourself from hazards and  create a safer  computer work environment.Note:  This information  includes references to power  adapters and  batteries. In addition  to notebook computers, some products (such  as speakers and  monitors)  ship with external  power  adapters. If you have such  a product, this information  applies to your product. In addition, computer products contain a coin-sized internal battery that  provides power  to the system clock even  when  the computer is unplugged, so the battery safety  information  applies to all computer products.
 
Conditions that require immediate actionProducts can  become damaged due to misuse or neglect. Some product damage is serious enough that the product should not be used again  until it has  been inspected and, if necessary, repaired  by an authorized servicer.As with any electronic device, pay close attention to the product when  it is turned on.  On very rare occasions, you might notice an odor or see a puff of smoke or sparks vent from your product. Or you might hear sounds like popping, cracking or hissing. These conditions might merely  mean that an internal electronic component has  failed in a safe and controlled manner.  Or, they might  indicatea potential safety issue.  However, do not take risks  or attempt to diagnose the situation yourself. Contact the Customer Support  Center  for further guidance. For a list of Service and Support  phone numbers, see the following Web site:http://www.lenovo.com/support/phoneFrequently  inspect your computer and its components for damage or wear  or signs of danger. If you have any question about  the condition of a component, do not use the product. Contact the Customer Support  Center  or the product manufacturer for instructions on how  to inspect the product andhave  it repaired,  if necessary.In the unlikely event that you notice any of the following conditions, or if you have  any safety concerns with your product, stop using  the product and unplug it from the power source and telecommunication lines  until you can  speak to the Customer Support  Center  for further guidance.  Power  cords, plugs,  power  adapters, extension cords, surge protectors, or power  supplies that  are cracked, broken, or damaged.  Signs  of overheating, smoke, sparks, or fire.  Damage to a battery (such as cracks, dents, or creases), discharge from a battery, or a buildup  of foreign substances on the battery.  A cracking, hissing  or popping sound, or strong odor  that comes from the product.  Signs  that liquid has  been spilled or an object has  fallen onto  the computer product, the power  cord  or power  adapter.  The computer product, power  cord,  or power  adapter has  been exposed to water.  The product has  been dropped or damaged in any way.  The product does not operate normally when  you follow the operating instructions.Note:  If you notice  these conditions with a product (such as an extension cord) that is not manufactured  for or by Lenovo,  stop  using that product until you can contact the product manufacturer for further instructions, or until you get  a suitable replacement.Safety guidelinesAlways observe the following precautions to reduce the risk of injury and  property damage.Service and upgradesDo not attempt to service a product yourself unless instructed to do so by the Customer Support Center or your documentation. Only use  a Service  Provider  who is approved to repair your particular product.Note:  Some computer parts can  be upgraded or replaced by the customer. Upgrades typically are referred to as options. Replacement parts approved for customer installation are referred to as Customer Replaceable Units, or CRUs.  Lenovo  provides documentation with instructions when  it is appropriate  for customers to install options or replace CRUs.  You must  closely  follow all instructions when  installing or replacing parts. The Off state of a power  indicator does not necessarily mean that  voltage  levels inside  a
 
product are zero.  Before  you remove the covers from a product equipped with a power  cord,  always  make sure  that  the power  is turned off and  that  the product is unplugged from any power  source. If you have any questions or concerns, contact the Customer Support Center.Although there  are no moving parts in your computer after the power  cord  has  been disconnected, the following warnings are required for your safety. CAUTION:Hazardous moving parts.  Keep  fingers and other  body  parts  away.CAUTION:Before replacing any CRUs, turn off the computer and wait three to five minutes to let the computer cool before opening the cover.Power cords and power adaptersDANGERUse  only the power cords and power adapters supplied by the product manufacturer.The power cords shall  be safety approved. For Germany,  it shall  be H05VV-F, 3G, 0.75 mm2,  or better.  For other  countries, the suitable types shall be used accordingly.Never  wrap a power cord  around  a power adapter or other  object. Doing  so can  stress the cord  in ways that can  cause the cord  to fray, crack,  or crimp.  This can  present a safety hazard.Always  route power cords so that they will not be walked on, tripped  over, or pinched by objects. Protect power cords and power adapters from liquids.  For instance, do not leave your power cordor power adapter near sinks, tubs,  toilets, or on floors  that are cleaned with liquid cleansers.Liquids can  cause a short  circuit,  particularly if the power cord or power adapter has  been stressed by misuse. Liquids also  can  cause gradual  corrosion of power cord terminals and/or  the connector terminals on a power adapter, which  can  eventually result  in overheating.Always  connect power cords and signal  cables in the correct order and ensure that all power cord connectors are securely and completely plugged into receptacles.Do not use any power adapter that shows corrosion at the ac  input pins  or shows signs of overheating (such  as deformed plastic) at the ac input pins or anywhere on the power adapter.Do not use any power cords where the electrical contacts on either  end show signs of corrosion or overheating or where the power cord  appears to have  been damaged in any way.
 
To prevent possible overheating, do not cover the power adapter with clothing or other  objects when  the power adapter is plugged into an electrical outlet.Extension cords and related devicesEnsure  that extension cords, surge protectors, uninterruptible power  supplies, and  power  strips  that you use are rated  to handle the electrical  requirements of the product. Never overload these devices. If power  strips are used, the load should not exceed the power  strip input rating.  Consult an electrician for more information if you have  questions about power  loads, power  requirements, and  input ratings.Plugs and outletsDANGERIf a receptacle (power  outlet)  that you intend  to use with your computer equipment appears to be damaged or corroded, do not use the outlet  until it is replaced by a qualified  electrician.Do not bend  or modify  the plug.  If the plug is damaged, contact the manufacturer to obtain a replacement.Do not share an electrical outlet  with other home or commercial appliances that draw large amounts of electricity; otherwise, unstable voltage might damage your computer, data,  or attached devices.Some products are equipped with a three-pronged plug.  This plug fits only into a grounded electrical outlet.  This is a safety feature. Do not defeat this safety feature by trying to insert  it into a non-grounded outlet.  If you cannot insert  the plug into the outlet,  contact an electrician for an approved outlet  adapter or to replace the outlet  with one  that enables this safety feature.

Power managementWhen you need to use  your computer away  from electrical  outlets, you depend on battery power  to keep your computer running.  Different computer components consume power  at different  rates. The more  you use  the power-intensive components, the faster  you consume battery power.Spend more  time unplugged with ThinkPad  batteries. Mobility has  revolutionized business by enabling you to take  your work wherever you go.  With ThinkPad  batteries, you will be able to work longer  without being  tied to an electrical  outlet.Checking the battery  statusThe battery status icon in the Windows  notification  area  displays the percentage of battery power  remaining.The rate  at which you use  battery power  determines how long you can  use  the battery of your computer between charges. Because of different  user  habits and  needs, it is difficult to predict how long a battery charge will last.  There are two main factors:  How much  energy  is stored in the battery when  you begin  to work.  The way you use  your computer. For example:  How often  you access the hard  disk drive or solid-state drive.  How bright  you make  the computer display.  How often  you use  the wireless features.To check for detailed battery status information,  do the following:  For Windows  7: Start  the Power  Manager program and  click the Battery  tab.  For Windows  8, do one  of the following:  Start  the Lenovo  Support program and  click Battery  Health  Start  the Lenovo  Settings program and  click Power.
 
Enabling  the battery  alarm on the Windows 7 operating systemFor the Windows  7 operating system, you can  program your computer so that when  the battery power  falls below  a certain  level, three  events occur:  the alarm goes off, a message is displayed, and  the LCD is turned off.To enable the battery alarm,  do the following:1.  Start  the Power  Manager program.2.  Click the Global Power Settings tab.3.  For Low battery  alarm or Critically low battery  alarm, set  the percentage of the power  level and  set the  action.Note:  If your computer enters sleep or hibernation mode when  the battery is low, but the alarm message has  not yet been displayed, the message will be displayed when  the computer resumes. To resume normal operation, when  the message is displayed, click OK.Using  the ac  power adapterThe power  to run your computer can  come either  from the lithium-ion (Li-ion) battery, or from ac power through the ac power  adapter. While you use  ac power,  the battery charges automatically.The ac power  adapter that comes with your computer has  two basic components:  The transformer pack  that  converts ac power  for use  with the computer.  The power  cord  that  plugs  into the ac outlet  and  into the transformer pack.Attention:  Using an improper power  cord  might cause severe damage to your computer.Connecting the ac  power adapterTo connect the ac power  adapter, do the following:Note:  Ensure  that  you perform  the actions in the order  in which they are listed.1.  Plug the ac power  adapter into an electrical  outlet.2.  Connect the power  cord  to the transformer pack.3.  Connect the ac power  adapter to the ac power  connector of the computer.Tips for using  the ac  power adapter  When the ac power  adapter is not in use,  disconnect it from the electrical  outlet.  Do not bind the power  cord  tightly around the ac power  adapter transformer pack  when it is connected to the  transformer.  Before  you charge the battery, make  sure  that its temperature is at least  10C (50F).  You can  charge the battery when  the ac power  adapter is connected to the computer. You need to charge the battery in any of the following situations:  When the battery icon in the Windows  notification  area  shows a low percentage of battery power remaining.  When the battery has  not been used for a long timeCharging  the batteryWhen you check battery status and  find that the percentage of power  remaining  is low or when  the power alarm alerts  you that the remaining  power  is low, you need to charge your battery.
 
If an ac outlet  is convenient, plug the ac power  adapter into it, and  then connect the ac power  adapter to the computer. The battery will be fully charged in about three  to six hours.  The charging time is affected by the battery size and the physical  environment. You can check the battery charging status at any time through the battery status icon in the Windows  notification  area.Note:  To maximize  the life of the battery, the computer does not start  recharging the battery if the remaining power  is greater than  95%.Maximizing  the battery  lifeTo maximize  the life of the battery, do the following:  Use the battery until the charge is completely depleted.  Recharge the battery completely before  using it. You can see  whether the battery is fully charged from the battery status icon in the Windows  notification  area.  Always use  power-saving modes, such  as sleep mode, and  hibernation mode.Managing the battery  powerTo achieve the best balance between performance and  power  saving,  adjust your power  plan settings. To access power  plan settings, do the following:  For Windows  7: Start  the Power  Manager program and  then click the Power Plan tab.

  Your finger is rough,  dry, or injured.  Your finger is dry.  Your finger is stained with dirt, mud,  or oil.  The surface of your finger is different  from when  you enrolled  your fingerprint.  Your finger is wet.  A finger is used that  has  not been enrolled.To improve  the situation, try the following:  Clean or wipe your hands to remove any excess dirt or moisture from the fingers.  Enroll and  use  a different  finger for authentication.  If your hands are dry, apply  lotion to them.For more information  on how to use  the fingerprint reader, refer to the help system of the Lenovo FingerprintManager program.Notice on deleting data from your hard disk drive or solid-state  driveSome of the data  stored on the hard  disk drive or solid-state drive might be sensitive. Handing  your computer over to someone else  without  deleting  the loaded software, such  as  operating systems and application software, might even  violate license agreements. Be sure  to delete data  stored on the hard  disk drive or solid-state drive before  you dispose of, sell, or hand  over your computer.You can  use  the following methods to delete data  from the hard  disk drive or solid-state drive:  Moving the data  to the Recycle  Bin, and  then  emptying the Recycle  Bin.  Deleting  the  data.  Formatting your hard  disk drive or solid-state drive, using  the software for initializing it.  Using the recovery program provided by Lenovo to bring the hard  disk drive or solid-state drive back  to the factory  default  settings.These  operations, however, only change the file location  of the data;  they do not delete the data  itself.  In other  words, the data  retrieval processing is disabled under  an operating system such  as Windows.  The data is still there,  even  though it seems to be lost.  Thus, it is sometimes possible to read  the data  by use  of special software for data  recovery. There is a risk that people of bad  faith might read  and  misuse the critical data  on hard  disk drives  or solid-state drives  for unexpected purposes.To prevent leakage of data, it is important that  you delete all the data  from the hard  disk drive when  you dispose of, sell, or hand  over your computer. You can  destroy the data  physically  by smashing the hard  disk drive with a hammer, or magnetically by means of strong magnetic power,  thus  making  the data  unreadable. But it is recommended that  you use  the software (payware)  or service (pay service)  developed for that purpose. The process might take  several hours.For disposing of data  on the hard disk drive or solid-state drive, Lenovo provides the Secure Data Disposaltool.  Go to http://www.lenovo.com/support to download the tool.If an Encryption solid-state drive or a Disk Encryption hard  disk drive is supported and  installed  in your computer, you can  logically dispose of all the data  on the drive in a short  time by erasing the cryptographic key.  The data  encrypted with the old key is not physically  erased but remains on the drive; however, it cannot be decrypted without the old key.  This feature  is enabled by ThinkPad  Setup Menu Extension Utility and  is available  as  a menu  item in ThinkPad  Setup.
 
Using  firewallsIf your system is preinstalled with a firewall program, it protects against computer Internet  security threats, unauthorized accesses, intrusions, and  Internet  attacks. It also protects your privacy.For more  information  about how to use  the firewall program, refer to the help information  system that comes with the program.Protecting data  against virusesYour computer is preinstalled with an antivirus  program so you can  detect and  eliminate  viruses. The antivirus  program is designed to help you detect and  eliminate  viruses.Lenovo provides a full version  of antivirus software on your computer with a free 30-day subscription. After30 days, you must  renew  the license to continue receiving  the antivirus software updates.For more  information  about how to use  your antivirus  software, refer to the help information  system of your antivirus  software.

The UEFI BIOSinitializes the hardware components, and  loads  the operating system and  other  programs.You can  update the UEFI BIOS by starting your computer from a flash update optical  disc  or a flash update program running in the Windows  environment. When you install a new program, a device  driver, or hardware, you might be informed  to update the UEFI BIOS.For instructions on how to update the UEFI BIOS, go to:http://www.lenovo.com/ThinkPadDriversUsing  system managementThis topic  is primarily intended for network  administrators.Your computer is designed for manageability, so that you can  redirect more  resources to better meet  your business objectives.This manageability, known  as  Total Cost  of Ownership (TCO), enables you to remotely  operate client computers in the same way as  you operate your own computer, such  as  turning  on a client computer, formatting  a hard  disk drive, and  installing a program.Once  the computer is configured and  operational, you can  manage it by using  the software and  the manageability features that are already  integrated into the client computer and  the network.
 
Desktop Management InterfaceThe UEFI BIOS of your computer supports an interface called  System Management BIOS (SMBIOS) Reference Specification, version  2.7.1.  SMBIOS provides information  about the hardware components of your computer. It is the responsibility of the UEFI BIOS to provide  information  about itself and the devices on the system board. This specification documents the standards for getting  access to this BIOS information.Preboot eXecution EnvironmentThe Preboot eXecution  Environment (PXE) technology makes the computer more  manageable by enabling the computer to start  from a server.  Your computer supports the personal computer functions that  PXE requires. For example, with the appropriate LAN card,  your computer can  be started from the PXE server.Note:  The Remote Initial Program Load (RIPL or RPL) function  cannot be used with your computer.Wake on LANThe network  administrator can  turn on a computer from a management console by using  the Wake onLAN feature.When the Wake on LAN feature  is enabled, many operations, such  as data  transfer, software updates, and Flash updates of the UEFI BIOS, can  be done  remotely  without  remote attendance. The updating process can  perform  after normal  working hours  and  on weekends, so that the users are not interrupted during work, and  the LAN traffic is kept  to a minimum.  It saves time and  increases productivity.Note:  If the computer is turned on through Wake on LAN, the computer starts follow the Network  Bootsequence.Asset ID EEPROMThe Asset  ID EEPROM contains information  about the computer configuration and  the serial numbers of the key components. It also  includes a number of blank fields where  you can  record information  about the end  users in your network.Setting management featuresTo enable a network  administrator to remotely  control  your computer, set  the following system-management features in the ThinkPad  Setup program:  Wake on LAN  Network  Boot  sequence  Flash  updateNote:  If a supervisor password has  been set,  you will be required to enter  the supervisor password when you start  the ThinkPad  Setup program.Enabling  or disabling the Wake on LAN featureWhen the Wake on LAN feature  is enabled and the computer is connected to a LAN, the network  administrator can start the computer remotely  from a management console, using a remote network-management program.To enable or disable the Wake on LAN feature, do the following:1.  Start  the ThinkPad  Setup program. See  Using the ThinkPad  Setup program on page 105.2.  Select Config  ? Network. The Network  submenu is displayed.3.  Select a corresponding option  for the Wake on LAN feature.4.  Press F10 to save  and  exit.
 
Defining  a Network  Boot  sequenceWhen the computer wakes on LAN, the computer starts from the device  as specified on the Network  Bootmenu,  and  then  follow the boot  order  list on the Boot  menu.To define  a Network  Boot  sequence, do the following:1.  Start  the ThinkPad  Setup program. See  Using the ThinkPad  Setup program on page 105.2.  Select Startup  ? Network  Boot.  The boot  device  list is displayed.3.  Select a boot  device  to make  it as  the top boot  priority.4.  Press F10 to save  and  exit.Note:  You can  press F9 to restore to the factory  default  settings.Checking the requirements for flash  updatesA network  administrator can  update the programs on your computer from a management console, if the following requirements are met:  The computer must  be started over LAN.  The computer must  be engaged in the Preboot eXecution  Environment (PXE).  A network-management program must  be installed  on the computer of the network  administrator.
 
Chapter  9. 	Preventing problemsAn important part  of owning  a ThinkPad  notebook computer is maintenance. With proper care,  youcan  avoid common problems. This chapter provides information  that  can  help you keep  your computer running  smoothly.	General  tips for preventing problems on page 119	Making sure  device  drivers  are current  on page 120	Taking care  of your computer on page 121General  tips for preventing problemsThis topic  provides the following tips to help you prevent computing problems:  If your computer is equipped with both  a hard  disk drive and  an M.2 solid-state drive, you are not recommended to use  the M.2 solid-state drive as a bootable device. The M.2 solid-state drive is designed and  developed for the cache function  purpose only. If you use  the M.2 solid-state drive as a bootable device, its reliability is not guaranteed.  Check  the capacity of your hard  disk drive from time to time.  If the hard  disk drive gets too full, theWindows  operating system will slow down  and  might produce errors. To check the hard  disk drive capacity, do the following:  Windows  7: Click Start ? Computer.  Windows  8: Open  the File Explorer and  click Computer.  Empty  your recycle  bin on a regular  basis.  Use disk defragment tool regularly on your hard  disk drive to improve  data  seek and  read  times.  To free up disk space, uninstall  unused programs.Note:  You also might want  to look for program duplication or overlapping versions.  Clean  out your Inbox, Sent,  and  Trash  folders  from your e-mail client program.  Back  up your data  at least  once a week.  If critical data  is present, it is a good  idea to perform  a daily backup operation. Lenovo  has  many backup options available  for your computer.  Rewritable optical drives  are available  for most  machines and  are easily installed.  Schedule system restore operations to take  a system snapshot periodically. For more  information  about system restore, see  Chapter 5 Recovery  overview on page 59.  Update device  drivers  and  UEFI BIOS when  needed.  Profile your machine at http://www.lenovo.com/support to keep  up to date  with current  drivers  and revisions.  Keep  up to date  for device  drivers  on other  non-Lenovo hardware. You might want  to read  the device driver information  release notes prior to updating for compatibility or known  issues.  Keep a log book.  Entries  might include  major hardware or software changes, driver updates, minor issues you have  experienced, and  how you resolved the minor issues.  If you ever need to run a recovery on your computer to return  the preinstalled contents onto  the machine, the following tips might help along  the way:  Remove all external  devices such  as the printer,  keyboard, and  so on.  Make sure  that your battery is charged and  your computer has  the ac power  connected.  Access ThinkPad  Setup and  load the default  settings.
 
  Restart the computer and  start  the recovery operation.  If your computer uses discs as  the recovery media,  do not remove the disc  from the drive until prompted to do so.  For suspected hard  disk drive issues, refer to Diagnosing problems on page 125 and  run a diagnostic test  for the drive before  you call the Customer Support Center. If your computer does not start  up, download the files to create a bootable self-test medium  from http://www.lenovo.com/hddtest. Run the test  and  record any messages or error codes. If the test  returns any failing error codes or messages, call the Customer Support Center with the codes or messages and  the computer in front of you.  A technician will assist you further.  If required, you can  find the contact information  about the Customer Support Center for your country  or region  at http://www.lenovo.com/support/phone. When calling the Customer Support Center, make  sure that you have  your machine model  type,  serial number, and  the computer in front of you.  Also, if the computer is producing error codes, it is helpful to have  the error screen on or the messages written down.Making sure device drivers are currentDevice drivers  are programs that  contain instructions for the operating system about how to operate or drive a certain  piece  of hardware. Each hardware component on your computer has  its own specific driver. If you add  a new component, the operating system needs to be instructed on how to operate that  pieceof hardware. After you install the driver, the operating system can  recognize the hardware component and  understand how to use  it.Note:  Because drivers  are programs, like any other  file on your computer, they are susceptible to corruption and  might not perform  correctly if corruption occurs.It is not always  necessary to download the latest  drivers.  However,  you should download the latest  driver for a component if you notice  poor  performance from that component or if you added a new component. This might eliminate  the driver as the potential cause of a problem.Getting  the latest drivers from the Web siteYou can  download and  install updated device  drivers  from the Lenovo Web site by doing  the following:1.  Go to http://www.lenovo.com/ThinkPadDrivers.2.  Select the entry for your computer and  then  follow the instructions on the screen to download and install necessary software.Getting  the latest drivers using  System UpdateThe System Update program helps  you keep  the software on your computer up-to-date. Update packages are stored on Lenovo servers and  can  be downloaded from the Lenovo Support Web site.  Update packages can  contain applications, device  drivers,  UEFI BIOS flashes, or software updates. When the System Update program connects to the Lenovo Support Web site, the System Update program automatically recognizes the machine type  and  model  of your computer, the installed  operating system, and  the language of the operating system to determine what updates are available  for your computer. The System Update program then displays a list of update packages and categorizes each update as critical, recommended, or optional  to help you understand the importance. You have  complete control  of which updates to download and  install. After you select the update packages you want,  the System Update program automatically downloads and installs  the updates without  any further intervention from you.The System Update program is preinstalled on your computer and  is ready  to run.  The only prerequisite is an active  Internet  connection. You can  start  the program manually,  or you can  use  the schedule featureto enable the program to search for updates  automatically at specified intervals.  You also  can  predefine scheduled updates to search by severity  (critical updates, critical and  recommended updates, or all updates) so the list you choose from contains only those update types that are of interest to you.
 
For more  information  about how to use  the System Update program, refer to the help information  system of the  program.Taking care of your computerAlthough your computer is designed to function  reliably in normal  work environments, you need to use common sense in handling  it. By following the important tips in this topic,  you will get the most  use  and enjoyment out of your computer.Be careful  about  where and how  you work  Store  packing materials safely out of the reach of children  to prevent the risk of suffocation from plastic bags.  Keep  your computer away  from magnets, activated cellular phones, electrical  appliances, or speakers(more than  13 cm or 5 inches).  Avoid subjecting your computer to extreme temperatures (below 5C/41F  or above 35C/95F).  Some appliances, such  as certain  portable desktop fans or air purifiers, can  produce negative ions.  If a computer is close  to such  an appliance, and  is exposed for an extended time to air containing negative ions, it might become electrostatically charged. Such  a charge might be discharged through your hands when  you touch  the keyboard or other  parts of the computer, or through connectors on I/O devices connected to the computer. Even though this kind of electrostatic discharge (ESD) is the opposite of a discharge from your body  or clothing  to the computer, it poses the same risk of a computer malfunction.Your computer is designed and manufactured to minimize any effects of electrostatic charge. An electrostatic charge above a certain  limit, however, can  increase the risk of ESD. Therefore, when  using  the computer close  to an appliance that can  produce negative ions, give special attention to the following:  Avoid directly exposing your computer to the air from an appliance that can  produce negative ions.  Keep your computer and  peripherals as far as possible from such  an appliance.  Wherever  possible, ground your computer to facilitate  safe  electrostatic discharge.Note:  Not all such  appliances cause a significant  electrostatic charge.Be gentle with your computer  Avoid placing  any objects (including paper)  between the display  and  the keyboard or the palm rest.  Your computer lid is designed to be opened and  used at an angle  slightly greater than 90 degrees. Do not open  the display  beyond 180 degrees, as this might damage the computer hinge.  Do not turn your computer over while the ac power  adapter is plugged in. This could  break  the adapter plug.Carry your computer properly  Before  moving your computer, be sure  to remove any media,  turn off attached devices, and  disconnect cords and  cables.  When picking up your open  computer, hold it by the bottom. Do not pick up or hold your computer by the  display.Handle  storage media  and drives  properly  If your computer comes with an optical  drive, do not touch  the surface of a disc  or the lens on the tray.  Wait until you hear  the CD or DVD click into the center pivot of the drive before  closing  the tray.  On your computer, use  only optical  drives designed for use  with the Serial Ultrabay  Enhanced bay.
 
  When installing the hard  disk drive, solid-state drive, or optical  drive, follow the instructions shipped with your hardware, and  apply pressure only where  needed on the device.  Turn off your computer before  you replace the hard  disk drive or solid-state drive.  After you replace the primary hard  disk drive or solid-state drive, reattach the cover  of the drive slot.  Store  your external  and  removable hard  disk drive or optical  drives  in the appropriate containers or packaging when  they are not being  used.  Before  you install a memory  card  such  as an SD card,  SDHC card,  SDXC card,  and  a MultiMediaCard, touch  a metal  table  or a grounded metal  object. This action  reduces any static  electricity  from your body.  Static  electricity  could  damage the device.  While transferring data  to or from a flash media  card,  such  as an SD card,  do not put your computer into sleep or hibernation mode before  the data  transfer is complete; otherwise, your data  could  become damaged.Take care in setting passwords  Remember your passwords. If you forget a supervisor or hard  disk password, Lenovo will not reset it, and you might have  to replace your system board, or hard  disk drive or solid-state drive.Taking care of the fingerprint  readerThe following actions could  damage the fingerprint reader or cause it not to work properly:  Scratching the surface of the fingerprint  reader with a hard,  pointed object.  Scraping the surface of the fingerprint  reader with your fingernail or anything  hard.  Using or touching the fingerprint  reader with a dirty finger.If you notice  any of the following conditions, gently clean  the surface of the fingerprint  reader with a dry, soft,  lint-free cloth:  The surface of the fingerprint  reader is dirty or stained.  The surface of the fingerprint  reader is wet.  The fingerprint  reader often  fails to enroll or authenticate your fingerprint.Register your computer  Register your ThinkPad  computer with Lenovo at http://www.lenovo.com/register. For more  information, see  Registering your computer on page 25.Be sure not to modify  your computer  Only an authorized ThinkPad  repair technician should disassemble and  repair your computer.  Do not modify or tape  the latches to keep  the display  open  or closed.Cleaning the cover of your computerOccasionally clean  your computer by doing  the following:1.  Prepare a mixture of a gentle  kitchen-use detergent. The detergent must  not contain abrasive powder or strong chemicals such  as acid or alkaline.  Use five parts water  to one  part  detergent.2.  Absorb  the diluted  detergent into a sponge.3.  Squeeze excess liquid from the sponge.4.  Wipe the cover  with the sponge, using a circular motion and  taking care  not to let any excess liquid drip.5.  Wipe the surface to remove the detergent.6.  Rinse  the sponge with clean  running  water.
 
7.  Wipe the cover  with the clean  sponge.8.  Wipe the surface again  with a dry, soft,  lint-free cloth.9.  Wait for the surface to dry completely and  remove any fibers from the cloth.Cleaning your computer keyboardTo clean  the computer keyboard, do the following:1.  Apply some isopropyl  rubbing  alcohol  to a soft, dust-free cloth.Note:  Avoid spraying cleaner directly onto  the keyboard.2.  Wipe each keytop  surface with the cloth.  Wipe the keys one  by one; if you wipe several keys at a time, the cloth might hook onto  an adjacent key and  possibly damage it. Make sure  that no liquid drips  onto or between the keys.3.  Allow to dry.4.  To remove any crumbs or dust  from beneath the keys,  you can  use  a camera blower  with a brush or cool air from a hair dryer.Cleaning your computer displayTo clean  the computer display,  do the following:1.  Gently wipe the display  with a dry, soft lint-free cloth.  If you see  a scratchlike mark on your display,it might be a stain  transferred from the keyboard or the TrackPoint pointing  stick when  the cover  was pressed from the outside.2.  Wipe or dust  the stain  gently with a soft,  dry cloth.3.  If the stain  remains, moisten a soft, lint-free cloth with water  or a 50-50  mixture of isopropyl  alcohol  and water  that  does not contain impurities.Note:  Avoid spraying cleaner directly onto  the keyboard.4.  Wring out as  much  of the liquid as  you can.5.  Wipe the display  again;  do not let any liquid drip into the computer.6.  Be sure  to dry the display  before  closing  it.

  Battery  Status ProfileUsage environment and your healthIntegrated wireless cards emit radio frequency electromagnetic energy  like other  radio devices. However,  the level of energy  emitted is far much  less  than  the electromagnetic energy  emitted by wireless devices likefor example mobile  phones.Due to the fact that integrated wireless cards operate within the guidelines found in radio frequency safety standards and recommendations, Lenovo believes they are safe  for use  by consumers. These  standards and recommendations reflect the consensus of the scientific  community and  result  from deliberations of panels and  committees of scientists who continually  review and  interpret the extensive research literature.In some situation or environment, the use  of integrated wireless cards might be restricted by the proprietor of the building or responsible representatives of the organization. These  situations and  areas might for example include:  Using the integrated wireless cards on board of airplanes, in hospitals or near  petrol  stations, blasting areas (with electro-explosive devices), medical implants or body-worn electronic medical devices, such as  pace makers.  In any other  environment where  the risk of interference to other  devices or services is perceived or identified  as  harmful.If you are uncertain of the policy that applies to the use  of wireless devices in a specific organization (such as airport  or hospital),  you are encouraged to ask  for authorization to use  integrated wireless cards prior to turning  on the computer.Locations of the UltraConnect wireless  antennasThinkPad  models feature  a diversified  antenna system built into the display  for optimal  reception, which enables wireless communication wherever you are. 1  Wireless LAN antenna (main)2  Wireless WAN antenna (main)3  Wireless WAN antenna (auxiliary)
