Brief power outage, perhaps?  Some BIOS have a selection of what to
do when power is restored from an outage, typical choices being to
start up, remain off, or return to the state before power was lost.
Others may offer only the first two, or be hardwired to one of them
with no opportunity to choose a different behavior.
