Chapter 4. General Checkout Attention The drives in the computer you are servicing might have been rearranged or the drive startup sequence changed. Be extremely careful during write operations such as copying, saving, or formatting. Data or programs can be overwritten if you select an incorrect drive. General error messages appear if a problem or conflict is found by an application program, the operating system, or both. For an explanation of these messages, refer to the information supplied with that software package. Before replacing any FRUs, ensure that the latest level of BIOS is installed on the system. A down-level BIOS might cause false errors and unnecessary replacement of the system board. For more information on how to determine and obtain the latest level BIOS, see "BIOS levels" on page 243. Use the following procedure to help determine the cause of the problem: 1. Power-off the computer and all external devices. 2. Check all cables and power cords. 3. Set all display controls to the middle position. 4. Power-on all external devices. 5. Power-on the computer. v Look for displayed error codes v Listen for beep codes v Look for readable instructions or a main menu on the display.

Run the Diagnostic programs. See Chapter 5, "Diagnostics," on page 45. v If you receive an error, replace the part that the diagnostic program calls out or go to "Diagnostic error codes" on page 56. v If the test stops and you cannot continue, replace the last device tested. Problem determination tips Due to the variety of hardware and software combinations that can be encountered, use the following information to assist you in problem determination. If possible, have this information available when requesting assistance from Service Support and Engineering functions. v Machine type and model v Processor or hard disk upgrades v Failure symptom - Do diagnostics indicate a failure? © Lenovo 2005, 2008.
