Chapter 6. Troubleshooting and diagnostics

This chapter provides basic troubleshooting and diagnostic information to help you solve problems that
might occur when using your server.
If your server encounters a problem, try to solve the problem by using the information in this chapter. If
the problem persists, you can get support from Lenovo. See Chapter 7 "Getting information, help, and
service" on page 107.

Troubleshooting procedure

Use the following information as a general procedure for diagnosing and troubleshooting problems you
experience with your server:
1. Verify that the power cords and the cables for all attached devices are connected correctly and securely.
2. Verify that the server and all attached devices that require ac power are connected to properly grounded,
functioning electrical outlets.
3. Verify that all installed hardware and attached devices are enabled in the BIOS settings of your server.
For information about accessing and changing the BIOS settings, see "Using the Setup Utility program"
on page 25.
4. If the server is not working after you have added new software or installed/replaced a component,
remove or reinstall it to see if the problem could be solved.
5. Turn on the server and press Esc as soon as you see the logo screen to view any diagnostic messages.
6. Download and use a diagnostic program to diagnose problems. See "Lenovo ThinkServer Diagnostics"
on page 10.
7. Refer to "Basic troubleshooting tables" on page 103 and follow the instructions for the type of problem
you are experiencing. If the basic troubleshooting information does not help you resolve a problem,
continue with the next step.
8. Try using a previous server configuration to see if a recent change to hardware or software settings has
caused a problem. Before restoring your previous configuration, capture your current configuration in
case the older configuration settings do not solve the problem or have adverse effect.
9. Use an antivirus program to see if your server has been infected by a virus. If the program detects a
virus, remove the virus.
10. If none of these actions solve the problem, seek technical assistance. See Chapter 7 "Getting
information, help, and service" on page 107.
