Power button got stuck, couldn't press down any longer plus battery was dying.
Replaced the battery, the power button, and the sensor cable. Followed all the directions as carefully as I could. Everything works fine!
Be careful, take your time, I got the Pro Tech Tool kit and screw mat for it. Also, take good pictures of your stuff every step of the way you can, at one point as I was putting the logic board back in, the rubber bumper on the end of it that protects the cables from wear and tear, fell out. I didn't know where it came from, so I looked at a pic I took during disassembly and luckily found where it fit.
