Chapter 1. Safety information This chapter presents following safety information that you need to be familiar with before you service a ThinkPad notebook computer.
• Find the room emergency power-off (EPO) switch, disconnecting switch, or electrical outlet. If an electrical accident occurs, you can then operate the switch or unplug the power cord quickly. • Do not work alone under hazardous conditions or near equipment that has hazardous voltages. • Disconnect all power before: – Performing a mechanical inspection – Working near power supplies – Removing or installing main units • Before you start to work on the machine, unplug the power cord.
Consider these conditions and the safety hazards they present: • Electrical hazards, especially primary power (primary voltage on the frame can cause serious or fatal electrical shock) • Explosive hazards, such as a damaged CRT face or a bulging capacitor • Mechanical hazards, such as loose or missing hardware To determine whether there are any potentially unsafe conditions, use the following checklist at the beginning of every service task.
– When working on a double-insulated or battery-operated system, use an ESD common ground or reference point. You can use coax or connector-outside shells on these systems. – Use the round ground prong of the ac plug on ac-operated computers. Grounding requirements Electrical grounding of the computer is required for operator safety and correct system function. Proper grounding of the electrical outlet can be verified by a certified electrician.

Important notice for replacing a system board Some components mounted on a system board are very sensitive. Improper handling of a system board can cause damage to those components, and may cause a system malfunction. Attention: When handling a system board: • Do not drop a system board or apply any excessive force to it. • Avoid rough handling of any kind. • Avoid bending a system board and hard pushing to prevent cracking at each BGA (Ball Grid Array) chipset.

Chapter 3. General checkout This chapter introduces following information: • “What to do first” on page 23 • “Checkout guide” on page 24 – “Lenovo Solution Center” on page 24 – “Quick test programs” on page 24 – “UEFI diagnostic program” on page 25 – “Bootable diagnostic programs” on page 25 • “Power system checkout” on page 26 Before you go to the checkout guide, be sure to read the following important notes. Important notes: • Only certified trained personnel should service the computer.
Before checking problems with the computer, determine whether the damage is covered under the warranty by referring to the following list: The following are not covered under warranty: • LCD panel cracked from the application of excessive force or from being dropped • Scratched (cosmetic) parts • Distortion, deformation, or discoloration of the cosmetic parts • Plastic parts, latches, pins, or connectors that have been cracked or broken by excessive force • Damage caused by liquid spilled into the system •
The quick test programs are applicable on the following operating systems: • Microsoft® Windows® 8.1 • Microsoft Windows 7 • Microsoft Windows XP • Microsoft Windows Server® 2003 • Microsoft Windows Server 2008 To download and install a quick test program, go to http://www.lenovo.com/diags, and follow the instructions on the Web site. To run a test using quick test program, do the following: 1. Go to the C:\SWTOOLS\ldiag directory. 2. Double-click the gui_lsc_lite.exe file. 3.
the internal storage devices. To use the bootable diagnostic programs, you can create a bootable diagnostic medium on a USB device or CD. To create a bootable diagnostic medium, do the following: 1. Go to: http://www.lenovo.com/diags. 2. Click Lenovo Bootable Diagnostics. 3. Follow the instructions on the Web site to create a bootable diagnostic medium on a USB device or CD.
Checking the ac power adapter You are here because the computer fails only when the ac power adapter is used. • If the system status indicator (the indicator in the ThinkPad logo or the indicator in the center of the power button) does not blink three times when an ac power source is connected, check the power cord of the ac power adapter for correct continuity and installation. • If the computer does not charge during operation, go to “Checking operational charging” on page 27.
Note: If the battery pack becomes hot, it may not be able to charge. Remove it from the computer and leave it at room temperature for a while. After it cools down, reinstall and recharge it. To check the battery pack, do the following: 1. Power off the computer. 2. Remove the battery pack and measure the voltage between battery terminals 1 (+) and 7 (-). See the following figure: 1(+) 2(+) 5 3 4 6(-) 7(-) Terminal Voltage (V dc) 1, 2 + 0 to + 12.6 6, 7 Ground (-) 3.
Chapter 4. Related service information This chapter presents following information: • “Restoring the factory contents by using the product Recovery Disc Set” on page 29 • “Using the Windows recovery programs on the Windows 8 and Windows 8.1 operating systems” on page 30 • “Passwords” on page 33 • “Power management” on page 34 • “Symptom-to-FRU index” on page 36 Service Web site: When the latest maintenance diskette and the system program service diskette become available, they will be posted on: http://www.
Note: The rest of the recovery process is fully automated and no action from you is required. The computer will restart into the Microsoft Windows desktop several times and you might experience periods when no activity is apparent on the screen for several minutes at a time. This is normal. 9. When the recovery process completes, the Welcome to Microsoft Windows screen is displayed. Follow the instructions on the screen to complete the Windows setup. 10.
1. Depending on the operating system, do one of the following: • For Windows 8: Move your pointer to the top-right or bottom-right corner of the screen to display the charms. Click Settings ➙ Change PC settings ➙ General. • For Windows 8.1: Move your pointer to the top-right or bottom-right corner of the screen to display the charms. Click Settings ➙ Change PC settings ➙ Update and recovery ➙ Recovery. 2. In the Remove everything and reinstall Windows section, click Get started.
It is recommended that you create recovery media as early as possible. Once you create recovery media, keep them in a safe place and do not use them to store other data. Creating recovery media To create recovery media, you need a USB drive with at least 16 GB of storage. The required USB capacity depends on the size of the recovery image. Attention: Creating recovery media will delete anything stored on the USB drive. To avoid data loss, make a backup copy of all the data that you want to keep.
3. Select a preferred language and then select a preferred keyboard layout. 4. Click Troubleshoot to display the optional recovery solutions. 5. Select a corresponding recovery solution according to your situation. For example, select Reset your PC if you want to reset your computer to the factory default settings.
