Hibernate. This sleep state reduces power consumption to a minimum by writing all data in system memory to a hard
drive and then removing system power. Waking up from this state restarts the computer, and the memory contents
are restored. Operation then resumes where the computer left off when it entered the hibernation state.
This state is not supported by Windows NT 4.0.

All components installed in the computer must support this feature and have the appropriate drivers loaded to
enter hibernation. For more information, see the manufacturer's documentation for each component.
Shutdown. This sleep state removes all power from the computer except a small auxiliary amount. As long as the
computer remains connected to an electrical outlet, it can be automatically or remotely started. For example, the Auto
allows the computer to automatically start at a specified time. Also, your network
administrator can remotely start your computer using a power management event such as Remote Wake Up.
The following table lists the sleep states and the methods you can use to wake the computer from each state.
