I did a search and couldn't really find any information so here i am posting. So, this has happened a couple times. I have put the tablet to sleep, when i go to use it again the screen will not turn on. I hear the fan running and when i press the windows button on the SP3 i feel it vibrate but nothing. I usually hold down the power button and restart the machine. I had similar problems on my SP2, with it turning on while in sleep but the screen always went on. I am considering going back and enabling hyper V and just put the machine into hibernate but i see mentions of the pros and cons. I did try it over the weekend and the main con i encountered was my wifi not enabling automatically... Any input/thoughts/experiences?
