Understanding Standby, Hibernation
and Shutdown
This section describes Standby, Hibernation, and shutdown and
explains when to implement them. Standby, Hibernation, and
shutdown procedures are provided later in the chapter. Standby
and Hibernation are energy-saving features that can be initiated
by you or by the system.
Standby
Standby reduces power to system components that are not in use.
When Standby is initiated, your work is saved in random access
memory (RAM) and the screen is cleared.
Saving your work before initiating Standby is not usually
necessary, but is a recommended precaution.
When the notebook is in Standby, the power/standby light
flashes.
When you resume from Standby, your work returns to the screen
where you left off.
Hibernation
Hibernation saves system memory to the hard drive, takes a
snapshot of the notebook image, then shuts down the notebook.
When you resume from Hibernation, your work returns to the
screen exactly as you left it.
