Power
Initiating Standby, Hibernation or
Shutdown
The following sections describe when to initiate Standby or
Hibernation and when to shut down your notebook.
When Leaving Your Work
Initiate Standby for shorter times and Hibernation for longer
times or for more power conservation.
The amount of time a battery pack can support Standby or
Hibernation or hold a charge varies by notebook configuration
and the condition of the battery pack.
■ Initiating Standby clears the screen and uses less power than
leaving the notebook on. Your work returns quickly to the
screen when you resume from Standby.
■ Initiating Hibernation clears the screen and uses much less
power than Standby. Returning to work saved in Hibernation
takes longer than returning to work saved in Standby but is
faster than returning to your place manually after restarting
the notebook.
To extend the life of the battery pack when the notebook will be
unused and unplugged for an extended period, shut down the
notebook, remove the battery pack, and store it in a cool, dry
location.
When External Power Supply Is Uncertain
If an external power supply is uncertain—for example,
because of an electrical storm—save your work, and then
initiate Hibernation, shut down the notebook, or work off of
battery power.
