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 con ict 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 103.
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.
