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:
1.
Reconnect the touchpad cables.
2.
Replace the touchpad.
3.
Replace the main 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.
NOTE: 
 Perform the FRU replacement or actions in the sequence shown in 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.
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 88.
The following lists the error messages that the BIOS displays on the screen and the error symptoms classified 
by function. 
NOTE: 
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. 
NOTE: 
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.

Intermittent Problems
Intermittent system hang problems can be caused by a variety of reasons that have nothing to do with a 
hardware defect, such as: cosmic radiation, electrostatic discharge, or software errors. FRU replacement 
should be considered only when a recurring problem exists.
When analyzing an intermittent problem, do the following:
1.
Run the advanced diagnostic test for the main board in loop mode at least 10 times.
2.
If no error is detected, do not replace any FRU.
3.
If any error is detected, replace the FRU.  Rerun the test to verify that there are no more errors. 
Undetermined Problems
The diagnostic problems does not identify which adapter or device failed, which installed devices are incorrect, 
whether a short circuit is suspected, or whether the system is inoperative.  
Follow these procedures to isolate the failing FRU (do not isolate non-defective FRU).
NOTE: 
Verify that all attached devices are supported by the computer.
NOTE: 
Verify that the power supply being used at the time of the failure is operating correctly. (See “Power 
System Check” on page 79):
1.
Power-off the computer.
2.
Visually check them for damage. If any problems are found, replace the FRU.
3.
Remove or disconnect all of the following devices:
!Non-Acer devices
!Printer, mouse, and other external devices
!Battery pack
!Hard disk drive
!DIMM 
!CD-ROM/Floppy diskette drive Module
!PC Cards
4.
Power-on the computer.
5.
Determine if the problem has changed.
6.
If the problem does not recur, reconnect the removed devices one at a time until you find the failing FRU.
7.
If the problem remains, replace the following FRU one at a time. Do not replace a non-defective FRU:
!Main Board
!LCD assembly
