Today I shut the lid of my MBP to put it to sleep. Nothing different from what I always do. A little while later I notice the MBP felt like it was running when I touched it. It was vibrating from the HD running. I didn't think much of this. I just now tried to turn my MBP on and it wouldn't. I decide to plug it in. When it turned on it did so for about 2 seconds, turned off, then turned back on. It then took a long time to boot up. When it finally did boot, it told me that the clock was all out of whack and I noticed tons of my settings had been reverted to default. I then check the battery to see that it is charging but the level is at 1%! When I shut the MBP lid earlier to put it to sleep the battery was at least 50%. Could someone tell me what the heck is going on??
