Sony Vaio Z (590) coming out of hibernate during night for no reason

I put my new laptop into hibernate and into my laptop bag. At about 3 am (I looked at event log) it seems to over the last few days come out of hibernation and come on. Within 10 minutes it goes back to sleep/hibernate. Thoughts? This happens while I am not even touching it. Would this have caused any damage (heat while in bag)? I doubt it but it is new and I am paranoid! Also for now I am just shutting down if the laptop is not plugged in and not in use.

 

Sounds like You need to turn off the stupid Windows scheduled tasks...or actually shut down your laptop instead of hibenate. Yes, it could hurt your laptop if it's automatically updating your IE7 to IE8 inside a backpack.

 

I disabled windows update (ran exactly at 3am). It only did this for two days (3AM wake up) and per the logs was only running for 5-10 minutes tops. Any chance this caused any issue? It is in a light computer bag (not leather) and the room is airconditioned... I am not sure if 5-10 minutes would have caused any perceivable damage.

 

When this once happened to me, the overheating caused half my screen to turn black. Once it cooled, it went back to being normal, but the laptop was almost too hot. I noticed that the areas that turned black had lost bit of its brightness compared to rest of the screen. Thankfully, I replaced the screen much later on.

 

Wow. How long was it overheating? Mine did not have anything obvious wrong with it (was warm but not "hot") but who knows...

 

Well problem with mine was that, I had both sleep mode and hibernation mode enabled. So, when I put it in sleep mode, and it tried to go into hibernation mode, it woke up first, froze, and couldn't go into hibernation mode. So, it started overheating. I had it inside a sleeve, and sleeve inside a laptop bag. It was like that for 15-20 minute at least.
