Cause
If in the S5 state due to a powerbutton override or THRMTRIP#, the possible wake events
When the WAKE# pin is active and the PCI Express device is enabled to wake the system,
are due to Power Button, Hard Reset Without Cycling (See Command Type 3 in

This is a wake event from S5 only if the sleep state was entered by setting the SLP_EN and
SLP_TYP bits via software, or if there is a power failure.
