Sometimes - even when my SP2 is OFF, the screen turns on to a black screen and then off after a few seconds, and when I turn my surface back on in desktop mode it says "the display drivers have stopped working and have restarted". Last night I went to bed at 26% battery and woke up to 18%. Something tells me this kept happening in the night and hurt my battery. Anyone know what gives? Also, does anyone know if there's a battery graph (like android) where I can see my battery stats plotted over time? Other then these... weird issues... and worse battery life aside, I LOVE this thing!
