I see a lot of people posting about their computer won't turn on after putting it to sleep, but I have the opposite problem. Mine won't stay asleep. I have it enter sleep mode, it goes to sleep for maybe 30 seconds, then wakes back up. I checked the sleep settings and even disconnected my mouse and keyboard to see if they were sending wake up signals but nothing helped. This only started a few days ago when I accidently put my computer into hibernate instead of sleep. I don't really know what the difference is, but it acted the same as if I had shut it down completely. I turned it on the next day and it worked fine, but later found that my sleep problem started.
