Hi, I've recently had an issue with my MBP. It's a first generation MBP and this issue came out of nowhere. I did not install any new hardware/software. Whenever I try to put my laptop to sleep.. the white light comes on for 3 seconds, and the cd drive makes a spin noise, and the laptop wakes up. This happens when I fold my laptop down to sleep, as well as going to apple>sleep. So far, I've tried disabling bluetooth, airport. I've also tried without the power supply in, and with it in. I've tried repairing disc permissions.. I've tried installing OS X from the discs that came with the laptop (I didn't format the HD though)... Any other suggestions?
