Hi all, regular problem with my i5 SP3 is that it won't turn on after going to sleep sometimes. Common problem I know, but here's the unique behaviour I haven't seen anyone write about: When it's dead, plugged into charger and charge light on: - if I press the power button, the charge light instantly turns off for 1sec then back on. - if I hold the power button down indefinitely, or power+vol, the charge light will flick off for 1sec every 10 seconds. Surely this means something?? Further info: - Only way I have ever gotten it back on is to mess around with the 2 button resets, give up, then come back to it days later and bam it turns on! (sometimes). Hardly a viable long term solution.. - Has done this on both win8.1 and 10 - unlike others stuck in sleep, my windows button does not vibrate on touch. - never had problems with charging. Power brick seems to be fine except my phone never seems to like charging from the usb socket. - when surface eventually turns back on it is always at full charge. - when it turns back on the clock is always wrong ie says the time from a few days ago when it would've gone to sleep/got stuck in sleep. - I have previously called support and gone through the 2 button resets with no success, ordered a replacement, only to have mine turn back on as I was packing it up to ship back to Microsoft.. Would appreciate any help. It happens once a week now. I just think surely the light turning off and on indicates it's aware of me pressing the power button. Surely it means something?
