Using power-saving states

The computer has two power-saving states enabled at the factory: Sleep and Hibernation.
When Sleep is initiated, the power light blinks and the screen clears. Your work is saved to memory,
letting you exit Sleep faster than exiting Hibernation. If the computer is in the Sleep state for an extended
period or if the battery reaches a critical battery level while in the Sleep 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.
