G73Jw Keeps going into hibernation

While doing semi intensive things, such as re-encoding audio, my laptop keeps going into hibernation. I've had this laptop since October and I would have to say I never had this issue for the first 6 months. I know this has to do with over heating of some sorts, because again, it only happens when doing cpu intensive things. I haven't played graphics intensive games for a while so I believe it has more to do with the CPU than the GPU. I have dusted the vents, and reinstalled Windows 7 multiple times.

Right now, I'm currently idling at around 50c for all cores, gpu is at 57c. Earlier, while re-encoding some audio, the cpu temps rose to around 85c, never saw it get to 90c, yet it still went into hibernation a few times. I can wake it back up within a few seconds, so I'm wondering is there something wrong with my laptop?

Thanks in advance!

 

Check your fan and vent areas for dust, blow it out with some compressed air.

 

If it was temp related wouldn't it just switch off instead of going into hibernation..?

 

Oops I didn't read the post correctly. Yeah this sounds like possibly a software problem.

Try reinstalling (or uninstalling) power4gear as a start.

 

If the reinstall or removal (my preference) of Power4Gear does not fix the issue I would disable hibernation (assuming you do not use it)
How to disable and re-enable hibernation on a computer that is running Windows

 

Thanks for the quick replies. I usually run my laptop docked to a 24inch hdmi monitor with the laptop lid closed. My laptop is not set to sleep while plugged in (when I close the lid), but I decided to run the test encoding with the screen lid open. Been encoding for over and hour now and not one hibernation. Wow!

So it has to do with running cpu intensive programs with the lid closed, that triggers hibernation. So although I haven't solved my issue, I at least know what's causing it.
