Question

Mouse Touch Pad

by musclehulk1 / October 12, 2016 2:49 PM PDT

My laptop touch pad is not functioning right. I can't control it and it has become super sensitive.

It is a Dell Inspiron 1545 that came out about 2009.

It is so sensitive that I don't even have to touch it to move the cursor on the screen. I can wave my finger or hand in the air over the laptop and it will move the cursor in a haphazard way. And no other part of my hand or finger is touching any part of the laptop. I've never seen anything like it and I have no clue what's going on.

I plugged in a USB optical mouse by "IHome" and it lit up but didn't work. I checked the touch pad settings and nothing was wrong. Is there any way to fix this? I already ran several virus checkers, ran cc cleaner that cleans out the cache and other things and went back to a restore point. Nothing helped. I have a feeling that its some kind of short circuit that's creating an electrical field because it is too weird that the mouse moves when I wave my hand around in the air.

Maybe someone has had experience with this and can advise because I have no clue.

That means I have to open it up which requires unscrewing about 50 screws and detaching the keyboard, wires and the film strip connector to the screen. I once ruined a laptop by opening it up and accidentally damaging the film strip connector. That will probably take me at least an hour if not more to do. And then, I'm not even positively sure that the touchpad is the problem. It could be something different. I would order a new touchpad, replace it and find out that it is not the problem.
I'm not afraid of opening things up like a desktop but the parts are so small on a laptop it's like working on a watch. It intimidates me and I am in great fear of forgetting how to put it back together or damaging something.
