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 the battery power.
• Sleep mode
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.
Depending on the 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, open the Lenovo Settings program and click Power ➙ 30 Day Standby.
To put your computer into sleep mode, go to the desktop and move your pointer to the top-right or
bottom-right corner of the screen to bring up the charms. Then click Settings ➙ Power ➙ Sleep.
• Hibernation mode
By using this mode, you can turn off your computer completely without saving les or exiting any
programs that are running. When the computer enters hibernation mode, all open programs, folders, and
les are saved to the hard disk drive or solid-state drive, and then the computer turns off.
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. Go to Control Panel and click System and Security.
2. Click Administrative Tools.

password or provide conrmation.

scheduled tasks are displayed.
