touchpad doesn't work, please help

Call support. There is no reason I can think of for this to happen. BTW - you have the mouse unplugged, right? I believe there is a setting to disable the track-pad when a mouse is plugged in. check System Preferences.

I know this is a worn out fixall but have you tried repairing your disk permissions?

I see one of three possibilities.

First, there's a problem with the trackpad device or cable connecting it. That it's connected is a good sign that this isn't it, but there could be a short somewhere in the device.

Second, there's a problem on the logic board, whatever hardware interprets trackpad movement is fried. Or the connections to the rest of the system.

Thirdly, it's a lower-level software issue. Reparing permissions might actually work, if your system isn't able to read some internal driver or something correctly. If you don't want to take it in right away, you could try performing a clean install or installing on another disk, and booting from there. Or booting from 9, if you have it.

You're probably SOL and going to have to take it in. Sorry

Well I don't know how exactly RAM could affect it but since you claim it started happening after you intalled the extra RAM, perhaps try taking it out..

Hmm, now it's working again, I suppose because I unplugged the USB mouse before I went to sleep.

I still recommend repairing permissions. Does it continue to work even after you restart? If not boot up off the 10.2 installation disk. Does it work while running off this disk? If so it's purely a software problem.

actually, my pop's ibook did this also.

have you installed RAM yourself? if so the track pad/clicker may have lost contact with the socket it is in.

in my pop's case, the whole entire socket became unsoldered formt he motherboard amazingly enough.

call apple, get them to fix it. it is prolly not a software issue.

This happened to me a couple weeks ago. At the time, I thought that the trackpad might have frozen (literally, I had just gotten back from Yosemite). Hearing this though, I wonder if it's a more widespread issue.

BTW, not only was it not working in X, it wasn't working in 9. It's definitely a hardware issue.

That's what I initially feared, but the fact that the trackpad works now indicates that it's probably a software problem rather than hardware. I'm probably going to try repairing permissions, but otherwise, the trackpad seems to be working now. very odd.

same with my pop's. it would connect and disconnect randomly. this happend for a week until it stop entirely.

Pound it with your fist a couple of times.
