190cs Trackpad Button Sticking
Posted by: jwse30 on 2020-06-04 12:41:04
The title sums it up; I've dug out a few of my old Macs during all this Covid stuff, with a 190cs being one of them. The whole machine seems to be working fine (I am sure the batteries aren't...)  with the exception of the trackpad button. About half the time it sticks in the pressed position. Are there any quick fixes to this? It looks like you have to take the whole machine apart to get to the thing. I am thinking of just using a mouse or seeing if I can find another GlidePoint trackpad as a workaround.

I am mostly using this machine to make floppies for my SE. I finally got the networking working pretty good, albeit slow, on the SE so I haven't really used the Powerbook in a few days.

Thanks in advance for any advice,

If theres corrosion from the battery it can damage the trackpad. I would take it apart and see whats going on under the trackpad

I just finished putting it all back together. Everything looks ok, (except for a few tabs that hold the palmrest in place that I assume I broke taking it apart). I put it back together, minus the battery pack, and it works a lot better now. The PRAM battery wasn't swollen or anything. I need to order a few replacement cells for those and rebuild it, since it looks like those aren't readily available anymore..

I did notice that the palmrest had a bit of a bulge on the left side before I tore into it, which was probably causing the button to bind up. It's still there, but it is not as pronounced.
