Initiating standby, hibernation or shutdown
The following sections explain when to initiate standby or hibernation and when to shut down the
computer.
NOTE You cannot initiate any type of networking communications or perform any computer
functions while the computer is in standby or hibernation.
When you leave your work
When standby is initiated, your work is stored in random access memory (RAM), and then the screen
is cleared. When the computer is in standby, it uses less power than when it is on. Your work returns
instantly to the screen when you resume from standby.
Hibernation saves your work to a hibernation file on the hard drive, and then shuts down the
computer. When the computer is in hibernation, it uses much less power than when it is in standby.
When the computer will be unused and disconnected from external power for an extended period,
shut down the computer and remove the battery pack to extend the life of the battery pack. For
details on battery pack storage, refer to "
Storing a battery pack."
When a reliable power supply is unavailable
Be sure that hibernation remains enabled, especially if you are operating the computer on battery
power and do not have access to an external power supply. If the battery pack fails, hibernation
saves your work to a hibernation file and shuts down the computer.
It is recommended that if you pause your work when the power supply is uncertain, you take one of
the following actions:
● Save your work, and then initiate standby.
● Initiate hibernation.
● Shut down the computer.
