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 45.
4.Go to the “Troubleshooting” on page 59 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:
•For Windows 7: Click Start ➙ Control Panel ➙ System and Security ➙ System ➙ System Protection ➙ System Restore.
•For Windows 8: 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 74 for more information.
•If the diagnostic program detects a hardware failure, contact the Lenovo Customer Support Center. See Chapter 11 “Getting information, help, and service” on page 75 for more information.
•If you are unable to run the diagnostic program, contact the Lenovo Customer Support Center. See Chapter 11 “Getting information, help, and service” on page 75 for more information.
•If the diagnostic program does not detect a hardware failure, continue with the next step.
