Acer DT85 manual 142, Testing the touchpad

CHAPTER 4: Troubleshooting

Testing the touchpad

If the touchpad doesn’t work, do the following actions one at a time to correct the problem.

To test the touchpad:

1Reconnect the touchpad cables.

2Replace the touchpad.

3Replace the system board.

Important

Do not replace a non-defective FRU.

After you use the touchpad, the pointer may drift 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.
