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.

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 26 • “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 8 • 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 Optical device test is not available when there is no optical drive installed on your computer. • The Recover Bad Sectors Tool is not available when there is no M.2 solid-state drive installed on your computer. Bootable diagnostic programs If the computer you are servicing is not installed with the UEFI diagnostic program, you can download a bootable diagnostic program from the Lenovo Support Web site.
6. Disconnect the ac power adapter and turn on the computer. If the computer can be turned on, it means that the battery pack is functional. If you suspect a power problem, see the appropriate one of the following power supply checkouts: • “Checking the ac power adapter” on page 27 • “Checking the battery and operational charging” on page 27 • “Checking the coin-cell battery” on page 28 Checking the ac power adapter You are here because the computer fails only when the ac power adapter is used.
To check whether the battery charges properly during operation, do the following: 1. Discharge the battery until the remained battery power is less than 50%. 2. Connect the computer to ac power to charge the battery. If the battery status icon in the Windows notification area indicates that the battery is not charging, remove the battery and let it return to room temperature. 3. Reinstall the battery. If the battery is still not charging, replace the battery pack. 4. Check the battery status icon again.

The recovery media are created successfully. Using recovery media If you cannot start your computer, or if you cannot start the Windows recovery image on your computer, use recovery media to recover your computer.
Attention: If the user hard disk password has been forgotten, check whether a master hard disk password has been set. If it has, it can be used for access to the hard disk drive. If no master hard disk password is available, neither Lenovo nor Lenovo authorized service technicians provide any services to reset either the user or the master hard disk password, or to recover data from the hard disk drive. The hard disk drive can be replaced for a scheduled fee.
To remove a user hard disk password that has been forgotten, when the supervisor password and master hard disk password are known, do the following: 1. Turn on the computer. 2. When the logo screen comes up, immediately press F1 to enter the ThinkPad Setup program. 3. Select Security. 4. Select Password. 5.
