DELL XPS-13 9360 requires hard power-down after sleep
I have a DELL XPS-13 9360 which won't resume from sleep mode - if it sleeps, I have to press and hold the power button (15 - 30 seconds, something like that) to hard restart the laptop in order to get it to boot. When I try and resume from sleep the keyboard backlight comes on, but nothing else happens, screen doesn't seem to wake up
I've drawn a blank trying to figure out what the problem is, event logger shows nothing between:
The system is entering connected standby Reason: Lid.
and when I hard-restart it
The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.
The only other thing I can see is very large (1GB+) system memory dump files being created but the timestamps don't match up well, so this may be a separate issue
I'm running Windows 10 version 1607 build 14393.693 fully updated, the laptop didn't originally have any issues sleeping but went back to Dell for a replacement keyboard (space bar didn't work properly) and the system was reimaged at that time and sleep hasn't worked since.
Thanks for any suggestions, this is a very frustrating issue 😞
