Question

Acer keyboard and touchpad stop working, PLEASE HELP

Feb 16, 2015 5:05PM PST

Hi everyone I was hoping someone could help me out.(I apologize for the lengthy thread) I'm having trouble with my Acer Aspire laptop (V3-551-8469 running Win.Cool. So both my keyboard and touchpad will stop working simultaneously, they will work normally after a quick restart or coming out of sleep mode. If I boot up the computer and don't move it they work fine. If I move the laptop or accidentally shake it, the keyboard and touchpad go off completely. The laptop USB ports still work however and the CPU continues working along with connecting an external mouse/keyboard. Still for the purpose of portability I need to do so without having to carry the extra junk. I had assumed it was a hardware failure between either of the two so I bought a new keyboard and touchpad and replaced them in myself, however, the problem still persisted. I have noticed something weird though, upon shaking/moving the laptop, my computer indicates that it is charging, as though I had just plugged it in to the Charger even though the charger isn't plugged in at all. It is at this point that the keyboard and touchpad go off. Now my question is: should I replace the motherboard entirely or the DC Jack??? I'm positive that it is not a software issue or a driver issue with the keyboard/mouse since I have reset all settings and updated drivers plenty of times.

The move or shake tells me it needs repair.

It doesn't tell us if it's the motherboard, keyboard or another part. If this was mine I'd remove the keyboard and then tape over the keyboard connection as I dusted the entire inside with canned air. Then I'd gently push any connections home, remove my tape that kept dust out of the keyboard connector, give that a very short blast with the canned air, use the contact cleaner on the keyboard cable and re-assemble and test. Hopefully the usual will get it going again.

This does not sound like a driver issue.

Tried the cleaning
Feb 17, 2015 2:40AM PST

Ok so I tried cleaning everything off very carefully (removing dust from the components and gently cleaning) but still nothing unfortunately:/ I can't pinpoint the problem, even if I add a little pressure on top of the laptop(I.e.pressing the keyboard hard, resting my hand on the Palmrest ) the computer reacts as if I just plugged in the charger and shuts off the keyboard/ mouse. Any idea as to what may be the problem?
