Sleep Wake failure in EFI Failure

Hi Jeff_W,

Thank you for the suggested support article, I've had a look on it and none of the alternatives applies to my problem.

My problem is that the computer won't wake up after going to sleep. Most of the times it will reboot a few seconds after pressing a button in the attempt to wake it. Some times I have to reset with long press on the power button.

Parts of error message after boot below.
