Broken keyboard cable
If iFixit does not have the part- Have them notify you when one comes in. I did that and never thought I would get a response - but I have the part, the Mac is back. Thanks
Replace the cable that connects the upper case, power button, trackpad, sleep sensor, and keyboard to the logic board of your model A1150 MacBook Pro 15" laptop.
