I guess thats not entirely true since it just booted into OS X, but it wasn't all day. I left the MBP in sleep mode and charging overnight (as usual). I woke up and went to use it, but it wouldn't wake up from sleep mode. The light in the front wasn't pulsating like it does when its in sleep mode, but rather, it was on constantly and dim. I held down the power button to turn it off completely, waited a minute, turned it back on. All I heard was the DVD drive make that noise when you turn the MBP on, and thats it, nothing on the screen, and the light was on, but dim again. I did that PRAM or SMC reset or whatever its called (removing battery and power and holding power button for 5-10 seconds). That didn't work either. I let the MBP sit for a few hours, with the battery in it, and the power disconnected. Tried it again, same thing, blank screen and the power light was on but dim. I took the battery out of it and didn't touch it until about 10 minutes ago. I put the battery back in it, and turned it on. This time, it booted, into OS X, as if nothing was wrong. I thought I would post this before putting it to sleep or anything. Never had this issue, and my MBP is out of warranty, so I would like to find out what I can before attempting to have Apple look at it. My MBP is a 2.16GHz C2D model, it has 2GB (1GB x 2) aftermarket ram (had it for a year), and I also have bootcamp installed and a 32GB Windows partition. I was thinking about getting rid of the Windows partition to see if that has anything to do with it, but I will wait for some responses first. If anyone has seen this before, please let me in on any info you have, much appreciated.
