Using Power Management

Stand By is a low power state where the processor is shut off, but the
rest of the machine remains powered. Waking up the workstation
from Stand By mode is faster than from Hibernate mode because the
RAM contents do not need to be restored. However, when the
workstation is in Stand By mode, it consumes more power than
Hibernate mode because the memory remains powered.
Hibernate (if enabled) makes the machine look and behave like it is
off except that it remembers the state it was in before hibernation
and can be awakened without a full operating system boot. This is
because the operating system copies the RAM contents out to a
special location on the hard disk before entering hibernation.
You must enable Hibernate mode through Power Options in the
Control Panel before it can be a shut down option.
