How does fast boot work when you use restart as opposed to shutdown? Does it work the same way, only instead of staying in the hybrid "sleep" mode, it immediately goes into the hybrid mode and then boots out? Does it do a full complete shutdown and then reboot?
In case anyone cares: I found the answer...
A reboot completes a full and complete shutdown of the computer prior to rebooting. No fast boot on a restart.
