Understanding the power-saving modes • Screen blank The computer display requires considerable battery power. To turn off power to the display, right-click the battery gauge icon from the Windows notification area and select Power off display. • Sleep In sleep mode, your work is saved to memory, and then the solid state drive or the hard disk drive and the computer display are turned off. When your computer wakes up, your work is restored within seconds. To put your computer into sleep mode, press Fn+F4. To return from sleep mode, press the Fn key. Depending on the computer model, your computer might support the 30 Day Standby function. When this function is enabled, the computer consumes even less power in sleep mode and takes only seconds to resume normal operation when you press the power button. For more information about the 30 Day Standby function, refer to the help information system of the Power Manager program. You also can use the combination to put the computer into hibernation mode or do-nothing mode by changing the settings in the Power Manager program. • Hibernation By using this mode, you can turn off your computer completely without saving files or exiting from any applications that are running. When you enter the hibernation mode, all open applications, folders, and files are saved to the hard disk, and then the computer turns off. Use the Power Manager program to configure how you want the computer enter hibernation mode.
