1.Dependant on operating system and PC configuration

When the computer is turned off, but left plugged in at the mains, the power consumption falls below 5 watts, but is not zero. A small trickle current continues to flow, supplying power to the CMOS memory, considerably extending the lifetime of the on-board battery.

If the computer is completely unplugged from the mains, the real time clock continues to operate, from the charge stored in the battery.
