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
• Damage caused by the improper insertion of a PC card or the installation of an incompatible card
• Improper disc insertion or use of an optical drive
• Fuses blown by attachment of a nonsupported device
• Forgotten computer password (making the computer unusable)
• Sticky keys caused by spilling a liquid onto the keyboard
• Use of an incorrect ac power adapter on laptop products
The following symptoms might indicate damage caused by nonwarranted activities:
• Missing parts might be a symptom of unauthorized service or modification.
• Check for obvious damage to a hard disk drive. If the spindle of a hard disk drive becomes noisy, the hard
disk drive might have been dropped or subject to excessive force.
Checkout guide
Use the following procedures as a guide in identifying and correcting problems with the ThinkPad notebook
computers.
Note: The diagnostic tests are intended to test only ThinkPad products. The use of non-ThinkPad products,
prototype cards, or modified options can lead to false indications of errors and invalid system responses.
1. Identify the failing symptoms in as much detail as possible.
2. Verify the symptoms. Try to re-create the failure by running the diagnostic test or by repeating the
operation.
Diagnosing problems
Many computer problems can be solved without outside assistance. If you experience a problem with your
computer, the first place to start is the troubleshooting information in your computer documentation. If
you suspect a software problem, see the documentation, including readme files and help information
systems, that come with the operating system or program. ThinkPad notebook computers come with a set
of diagnostic programs that you can use to help you identify hardware problems.

Notes:
• If you are using another Windows operating system rather than the Windows 7, you can find the latest
information about diagnostics for your computer at:

• If you are unable to isolate and repair the problem yourself after running Lenovo Solution Center, save and
print the log files created by the program. You need the log files when you speak to a Lenovo technical
support representative.
