The only peripheral I am using is the touch 2 cover. I would be using whichever GPU driver came with my device. I am really worried that this will happen again and want to get to the bottom of it! The device would have been *in* hibernate so that means it must have woken up for some reason. Is there a way I can see why?
Also I'll check out the Note. I really like my Surface but it's difficult to use it in a working environment!
I had something like this where it would either wake from sleep or hibernate and then stay on all night, thus draining the battery, from both the December and January firmware updates. This was fixed with the February firmware as far as I can tell since I haven't experienced it since then. Have you installed all of the firmware updates?
