CHAPTER 4: Troubleshooting

Touchpad Check
If the touchpad doesn’t work, do the following actions one at a time to correct
the problem. Do not replace a non-defective FRU.
To check the touchpad:
1
Reconnect the touchpad cables.
2
Replace the touchpad.
3
Replace the system board.
After you use the touchpad, the pointer drifts on the screen for a short time.
This self-acting pointer movement can occur when a slight, steady pressure
is applied to the touchpad pointer. This symptom is not a hardware problem.
No service actions are necessary if the pointer movement stops in a short
period of time.
Power-On Self-Test (POST) Error
Message
The POST error message index lists the error message and their possible causes.
The most likely cause is listed first.
This index can also help you determine the next possible FRU to be replaced
when servicing a computer.
If the symptom is not listed,
see “Undetermined Problems” on page 75 .
The following lists the error messages that the BIOS displays on the screen
and the error symptoms classified by function.
Important
Perform the FRU replacement or actions in the sequence shown in the
FRU/Action column. If the FRU replacement does not solve the problem, put
the original part back in the computer. Do not replace a non-defective FRU.
Important
Most of the error messages occur during POST. Some of them display
information about a hardware device, e.g., the amount of memory installed.
Others may indicate a problem with a device, such as the way it has been
configured.
Important
If the system fails after you make changes in the BIOS Setup Utility
menus, reset the computer, enter Setup and install Setup defaults or correct
the error.
