Power management
When you use your computer away from electrical outlets, you depend on battery power to keep your
computer running. Different computer components consume power at different rates. The more you use the
power-intensive components, the faster you consume battery power. Mobility has revolutionized business
by allowing you to take your work wherever you go. With ThinkPad batteries, you will be able to work longer
without being tied to an electrical outlet.
Using the battery power
You can use your battery power more ef ciently with the help of this introduction.
Checking the battery status
The battery status icon in the Windows noti cation area displays the percentage of battery power remaining.
The rate at which you use battery power will determine how long you can use the battery of your computer
between charges. Because each computer user has different habits and needs, it is dif cult to predict how
long a battery charge will last. There are two main factors:
How much energy is stored in the battery when you begin to work.
The way you use your computer:
How often you access the hard disk drive.
How bright you make the computer display.
To check for detailed battery status information, do one of the following:
Open the Lenovo Support program and click Battery Health .
Open the Lenovo Settings program and click Power .
