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 light blinks 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.
