Trackpad doesn't work but clicks
I have a 2008 MacBook where the trackpad doesn’t work and the cursor is stuck in the upper left corner but the clicking works.
I replaced the uppercase as I got it cheap and the trackpad worked at the beginning but then not sure what happened but it stopped working when putting everything back.
I then put back the old trackpad which I know worked before but was glitchy but now the same thing issue occurs, cursor frozen but clicking works. Cursor does move if I plug a USB mouse in and I also already tried the PRAM reset and no, I don’t have a bulging battery.
Aside from the trackpad connector that plugs into the logic board, is there something else on the logic board that controls the trackpad part?
Es esta una buena pregunta?
