Manage power

Use the information in this section to achieve the best balance between performance and power efficiency.

Check the battery status

The battery status icon
the current power plan, and access battery settings quickly.
Click the battery status icon to display the percentage of battery power remaining and change the power
mode. A warning message is displayed when the battery is low.

Charge the battery

When the remaining battery power is low, charge your battery by connecting your computer to ac power.
The battery is fully charged in about two to four hours. The actual charging time depends on the battery
capacity, the physical environment, and whether you are using the computer.
Battery charging is also affected by its temperature. The recommended temperature range for charging the
battery is between 10°C (50°F) and 35°C (95°F).
Note:
You can check the battery temperature in Lenovo Vantage or Lenovo PC Manager.
To maximize the life of the battery, once the battery is fully charged, it must discharge to 94% or lower
before it will be allowed to recharge again.
To extend your battery's lifespan, the battery may optimize its full charge capacity based on your usage.
After prolonged periods of limited use, full battery capacity may not be available until you discharge to as
low as 20% and recharge completely. For more information, refer to the power section of Lenovo
Vantage.

Set power button behavior

By default, pressing the power button puts the computer to sleep mode. However, you can change the
power button behavior in Windows Control Panel.
Step 1. Type Control Panel in the Windows search box and then press Enter. Open the control panel and
view by large or small icons.
Step 2. Select the power options and then click choose what the power button does.

A power plan

A power plan is a collection of power-saving settings made available by an operating system. With a power
plan, you can set idle time-outs for different hardware components to enter a low-power state. The default
power plan and some of its idle time-out settings are listed below for computer models pre-installed with
Windows.
The listed settings are active when the computer is connected to an electrical outlet. If your computer include
a built-in battery pack, a different collection of time-out settings is set to take effect when the computer is
operating on battery power.
