Charging The Battery; Managing The Battery Power; Power-Saving Modes - Lenovo ThinkPad 11e 3rd Gen User Manual

Note: If your computer enters sleep or hibernation mode when the battery power is low, but the alarm
message has not yet been displayed, the message will be displayed when the computer resumes. To return
to normal operation, when the message is displayed, click OK.

Charging the battery

It is recommended that you charge the battery when the battery power remaining is low, for example:
• When you find that the percentage of the remaining power is low
• When the power alarm alerts you
If an ac outlet is convenient, connect the ac power adapter to the computer and the ac outlet. Depending on
the battery size and the physical environment, the battery will be fully charged in about three to six hours.
The battery-status icon helps you identify that the battery is charging, and that the battery is fully charged.
Note: To maximize the life of the battery, the computer does not start recharging the battery if the remaining
power is greater than 95%.

Managing the battery power

To achieve the best balance between performance and power saving, adjust your power plan settings
by doing the following:
1. Go to Control Panel and change the view of Control Panel from Category to Large icons or Small icons.
2. Click Power Options.
3. Follow the instructions on the screen.

Power-saving modes

There are several power-saving 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.
• Screen-blank mode (for Windows 7 only)
The computer display requires considerable battery power. To turn off the power to the display and make
the computer enter screen-blank mode, right-click the battery gauge icon in the Windows notification
area and then select Power off display.
• Sleep mode
In sleep mode, your work is saved to memory, and then the internal storage drive and the computer display
are turned off. When your computer resumes to normal operation, your work is restored within seconds.
To put your computer into sleep mode, do the following:
– For Windows 7: Open the Start menu, click the arrow next to the Shut down button, and then 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 from any
programs that are running. When the computer enters hibernation mode, all open programs, folders, and
files are saved to the internal storage drive, and then the computer turns off.
To put the computer into hibernation mode, change your power plan settings by doing the following:
– For Windows 7: Open the Start menu, click the arrow next to the Shut down button, and then 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
