Troubleshooting procedure
Use the following procedure as a starting point for diagnosing problems you are experiencing with your
computer:
1. Verify that the cables for all attached devices are connected correctly and securely.
2. Verify that all attached devices that require ac power are connected to properly grounded, functioning
electrical outlets.
3. Verify that all attached devices are enabled in the BIOS settings of your computer. For more information
about accessing and changing the BIOS settings, refer to your Chapter 5 “Using the Setup Utility
program” on page 49.
4. Go to the “Troubleshooting” on page 32 and follow the instructions for the type of problem you are
experiencing. If the Troubleshooting information does not help you resolve a problem, continue with the
next step.
5. Try using a previously captured configuration to see if a recent change to hardware or software settings
has caused a problem. Before restoring a previous configuration, capture your current configuration in
case the older configuration settings do not solve the problem or have adverse affects. To restore a
captured configuration, open Control Panel, and then click System and Security ➙ System ➙ System
Protection ➙ System Restore. If this does not correct the problem, continue with the next step.
6. Run the diagnostic program. See “Lenovo Solution Center” on page 47 for more information.

See “Lenovo Support Web site” on page 28 for more information.
• If you are unable to run the diagnostic program, contact the Lenovo Customer Support Center. See
“Lenovo Support Web site” on page 28 for more information.
• If the diagnostic program does not detect a hardware failure, continue with the next step.
7. Use an antivirus program to see if your computer has been infected by a virus. If the program detects a
virus, remove the virus.
8. If none of these actions solve the problem, seek technical assistance. See “Lenovo Support Web
site” on page 28 for more information.
