Trackpad Button Issue

Mijn probleem

The problem I had was with the trackpad button, either it would not respond or would require much force, and or it would respond multiple times with one push.

Mijn oplossing

My Mac is a Powerbook G4 Aluminum, 15" 1.67 GHz. I used your instructions for removing the keyboard. I located the the printed circuit ribbon leading to the trackpad button. I removed the 2 phillips screws holding the button to the keyboard. I folded the ribbon over and was able to see the trackpad button. The button seemed to have 4 small openings where it was soldered to the printed circuit ribbon. I thought I could spray some contact cleaner into those openings. I first tape off the area so as not to effect other components. I sprayed the openings with a TV tuner spray that contained 1,1,1 Trichloroethane. I am not sure this chemical is allowed in California any more (something I acquire about 25 years ago). I continually activated the button and wipe off the excess spray before I reassembled the laptop. As far as I can tell the spray did not effect the other components and the trackpad is working fine at this time. I worked very slowly since this was the first time I had taken my Mac apart (about 3 hours of work). Sorry I did not take a photo.

Mijn advies

Make sure the spray you use does not have a detrimental effect on the other components.
