Restored MacBook keyboard & trackpad with an Upper Case Cable Replacement
MacBook Core Duo Upper Case Cable
Hat geantwortet auf: How to fix when battery corrodedVinegar is supposed to remove alkaline battery corrosion. I used a q-tip and vinegar to restore my Bose QC2s, and then was careful to never store them with the battery inside. Unfortunately, despite this, they developed the same problem again (not turning on when a good battery is inserted), and this time vinegar has not been able to make them work. I can barely see inside, but the anode at the bottom ("-" side) looks corroded brown rather than green. Perhaps a different issue. I can't believe how fragile these super expensive headphones have been. I'll try more drastic measures to clean inside there...not much to lose at this point.
Hat geantwortet auf: My Keyboard and trackpad not workingI have the same problem. I replaced the BlueTooth board in my MacBook Core Duo, and that required removing almost everything, including the keyboard/trackpad. After I reassembled everything, I was able to turn on the MacBook (a button which is on the keyboard) but now neither the keyboard or the trackpad work. I opened the machine again, checked the cable, unseated and reseated the connector, and turned the machine back on. It didn't help. I tried resetting the PRAM by holding the power button down ten seconds while off, until it came on and I heard the tone. That didn't help either. Neither did resetting the SMC (holding the power button down 5 seconds with the power disconnected and the battery removed). The only thing left for me to do, it seems, is replace the upper case cable in hopes that it was what failed during the machine maintenance. UPDATE: I replaced the Upper Case Cable, and now the keyboard and trackpad are back to working status. I suggest if you're having this problem, to try replacing this p...
