My Surface Pro 2 failed to turn on yesterday, after remaining on charge overnight.
It was not shut down overnight.
I was stuck with a black screen, and no combination of the power + volume button commands on the support site had any effect.
I noticed that the windows button was initially still responsive, causing the device to vibrate, but nothing else.
Due to this and the consistent heat being generated by the device, I assumed it was frozen, and attempted to shut it down, but no matter how long I help the power button, it didn't change.
The keyboard (touch cover 2) backlight still worked, and would even fade after inactivity.
I had logged a support request with Microsoft and organised a courier to pickup my device and return for service.
However, after leaving the device disconnected overnight, I have found that it will power on and functions normally.
This would lead me to assume that it was a software/UEFI issue, and not a hardware failure.
I have been unable to replicate the issue though any combination of locking the device, pressing the power button, or closing the cover.
Should I continue to return the device to MS, or should I proceed in the hope that this issue doesn't arise again?
