This has only started happening recently after approx 5 months from new trouble free period. Every time I shutdown using the on screen 'Shutdown' option, bottom left Windows 10 screen, the unit, as you would expect goes off, except now it shows the dim green light on the front indicating it has entered sleep or hibernation (can't tell the difference). When I turn it back on again using the side On/Off button nothing happens. The only way I can get the unit to start up is by taking the power lead out of the back, reinserting it then, press the power button at which point everything then powers on as normal. I have not changed any settings in either Windows or Minix that would account for this behaviour. Does anybody have any ideas please?
