gah! this is the most weird thing ever. melodrama aside - recently the screen will sometimes do either of the following: 1) when hibernating and I press the power button, the unit will turn on (the touch Windows button will vibrate the unit or the keyboard backlight will light up) but the screen stays black 2) the screen will show the Surface boot-up logo (the spinning dots) normally but then fail to transition to the login screen and just stay black. I usually have to hold the power button for 15s to turn the thing off and then when I turn it on again it will boot up ok. I've checked the Windows reliability monitor but all it says is 'windows did not shut down properly'. note that this ONLY happens when waking up from hibernate. has this happened to anyone else? thanks again!
