Hi there, I'm a newbie to this forum and haven't been able to find a solution to my specific problem(s) after searching the archives. I disassembled my 1st generation MacBook to repair a jammed optical drive. Well, now I have two new problems: The first is while testing my repaired optical drive (I tested it while the laptop was still partially disassembled, and the optical drive does now work) I noticed the track pad and keyboard were not functioning. Obviously the power button works, and the machine booted fine, but the trackpad and the entire keyboard don't work at all. I had to plug a mouse in to move the pointer. I should note that yes, the trackpad cable was indeed firmly plugged in. *However, at one point while trying to reassemble the top case, the trackpad cable detached from the plastic piece that plugs it into the logic board. I removed the plastic piece, slid it back into place over the wires of the trackpad cable and then plugged it back in to the logic board. So I'm wondering if this means I now need a new trackpad cable? The second problem is that upon full reassembly, the machine will not turn on. The power button simply doesn't work when the top case is firmly back in place and the rest of the machine (screws, l-bracket, battery, etc.) is completely reassembled. I have no idea what might be causing this. Any advice is very much appreciated. Thanks in advance!
