First, do you have a real problem or are you just preparing, in case?
Second, unless your PB360 is running firmware 15.1, it is actualy very stable.
Third, most lockups can be fixed with the reset button next to the battery.
The restore to factory condition hard reset is most useful when you've been tweaking system settings or exploring the envelope. And even then, it is rare to need to go that far.

Anyway, powering refers to connecting the 360 to a power source, say, a usb power adapter.
Powering up refers to turning the reader on.
