Hey guys, My Black MacBook (2007) has been having an odd issue lately. The trackpad and keyboard will randomly stop working, both on startup/wakeup and even sometimes mid-use. I had this happen mid-use to me this morning. Once the keyboard and track pad stop responding, there is no way to get them to become functional again. USB peripherals are tested working, and the power button on the top case still functions when the keyboard/trackpad have failed. I've been able to rouse the keyboard/trackpad back into a working state with PRAM resets and battery pulls, but I can't seem to isolate what exactly causes the problem in the first place Would a non-OEM battery possibly cause this? Faulty power adapter? Maybe loose ribbon cable? Anyone have any experience with a similar issue? Help is appreciated! Thanks!
