Did you check for Hibernation or Hybrid Sleep? That requires a brief press of the power button to wake the computer. Hibernation or Hybrid Sleep automatically kicks in after a long sleep. It looks like it is shutdown and pressing the power button starts what looks like a reboot but it is quicker than that and all open windows will reappear. 

Run the Dell Diagnostics to test all the hardware.
