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 7 “Using the Setup Utility program” on page 75.

4.Go to the “Troubleshooting” on page 92 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, do the following:

•On the Windows Vista operating system, click Start ➙ Control Panel ➙ System and Maintenance

➙ System ➙ System Protection ➙ System Restore.

•On the Windows 7 operating system, click Start ➙ Control Panel ➙ System and Security ➙ System ➙ System Protection ➙ System Restore.

If this does not correct the problem, continue with the next step.

6.Run the diagnostic programs. See “Diagnostic programs” on page 108 for more information.

•If the diagnostic programs detect a hardware failure, contact the Lenovo Customer Support Center. See Chapter 11 “Getting information, help, and service” on page 111 for more information.

•If you are unable to run the diagnostic programs, contact the Lenovo Customer Support Center. See Chapter 11 “Getting information, help, and service” on page 111 for more information.

•If the diagnostic programs do 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 Chapter 11 “Getting information, help, and service” on page 111 for more information.
