Setting power options

Using power-saving states

The computer has two power-saving states enabled at the factory: Suspend and Hibernation.
When Suspend is initiated, the power lights blink and the screen clears. Your work is saved to
memory, letting you exit the Suspend state faster than exiting Hibernation. If the computer is in the
Suspend state for an extended period or if the battery reaches a critical battery level while in the
Suspend state, the computer initiates Hibernation.
When Hibernation is initiated, your work is saved to a hibernation file on the hard drive and the
computer turns off.
CAUTION:
functionality, or loss of information, do not initiate Suspend or Hibernation while reading from or
writing to a disc or an external media card.
NOTE: You cannot initiate any type of networking connection or perform any computer functions
while the computer is in the Suspend state or in Hibernation.

Initiating and exiting Suspend

The system is set at the factory to initiate Suspend after a period of inactivity when running on battery
power or on external power.
Power settings and timeouts can be changed using Power Management in Control Center.

where you stopped working.
