Power-saving modes

There are several modes that you can use at any time to conserve power. This section introduces each mode
and gives tips on the effective use of battery power.
• Screen blank mode (for Windows 7 only)
The computer display requires considerable battery power. To enter screen blank mode, right-click the
battery-status icon in the Windows notification area and select Power off display.
• Sleep mode
In sleep mode, your work is saved to memory, and then the storage 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, do the following:
– For Windows 7: Open the Start menu and click the arrow next to the Shut down button. Click Sleep
from the menu displayed.
– For Windows 10: Open the Start menu, click
• Hibernation mode
By using this mode, you can turn off your computer completely without saving files or exiting any
programs that are running. When the computer enters hibernation mode, all open programs, folders, and
files are saved to the storage drive, and then the computer turns off.
To put the computer into hibernation mode, do the following:
– For Windows 7: Open the Start menu and click the arrow next to the Shut down button. Click
Hibernate from the menu displayed.
– For Windows 10: Define what the power button does first, and then press the power button to put the
computer into hibernation mode.
If you put your computer into hibernation mode with the wake-up function disabled, the computer does
not consume any power. The wake-up function is disabled by default. If you put your computer into
hibernation mode with the wake-up function enabled, the computer consumes a small amount of power.
To enable the wake-up function, do the following:
1. Open Control Panel, view Control Panel by Category, and then click System and Security.
Power, and then click Sleep.
