Hopefully this isn't a duplicate thread.... After a week of owning this great computer I closed the lid to put it to sleep last night (same as i do every night) and the sleep indicator light dimmed as it would when it goes to sleep. I heard the HD and fan turn off as normal. But as soon as the front light dimmed all the way the apple icon flashed for a split second and the HD started back up and the sleep indicator light stayed brightly lit for about 10-15 seconds. It would then dim again as if it was going to sleep and start this cycle all over again. I didn't realize this until i was laying in bed and heard my HD start up every few seconds. I tried restarting the computer and nothing changed. Nothing is running in my dock except for finder. I tried putting it to sleep with the lid open and it went to sleep, but then just came back awake within a few seconds. I went to click shutdown and it restarted. I tried to shutdown once more and it just restarted. I did a hard shutdown and then turned it on and tried to put it to sleep and it still was the same.... Any suggestions? I'm new to mac so I'm very naive with these still. Thanks... Edit: I'd also like to add that my computer now gets very very very hot on the bottom with nothing running. Not nearly as hot as a few days ago. I don't know if it's related.
