My SP2 will no longer hibernate when sleeping, but instead it wakes up. Actually, it does seem to enter hibernation, but then it immediately wakes from hibernation (the "Surface" logo and spinny dots are displayed). Another strange side effect of this behavior is that the "System" process seems to go crazy after waking causing 25%-30% CPU utilization. The system process does not seem "settle" on its own and only a restart will return the CPU utilization to normal. Windows has no idea what caused the wake up - powrcfg /lastwake gives no cause for the wake up. I have also tried disabling and re-enabling hibernation (powercfg /h) to no avail. Also, when I manually enter hibernation, it will successfully hibernate, but I am still stuck with the runaway system process after it wakes up. I had disabled hibernation in the power plan because it was occasionally causing the the display driver to crash. I figured that I would re-enable hibernation after the recent update to see if the driver problems went away. Any help would be greatly appreciated.
