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. Jeff
