When I experience weird power related problems (and problems with
reboot), I go right to the BIOS or UEFI and ensure the firmware is the
latest. UEFI is where the ACPI tables are located, and that affects
all power behavior. So I think your first step is to ensure the
firmware is up to date.
I also disable S3 and S4 sleep states in the firmware. In this case, I
don't want both the firmware and OS to try to control power states.
