Power management

When you need to 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.

Spend more time unplugged with ThinkPad batteries. Mobility has revolutionized business by enabling 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.

Checking the battery status

The battery status icon in the Windows notification area displays the percentage of battery power remaining.

The rate at which you use battery power determines how long you can use the battery of your computer between charges. Because of different user habits and needs, it is difficult 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. For example:

–How often you access the hard disk drive or solid-state drive.

–How bright you make the computer display.

–How often you use the wireless features.

To check for detailed battery status information, do the following:

•For Windows 7: Start the Power Manager program and click the Battery tab.

•For Windows 8, do one of the following:

–Start the Lenovo Support program and click Battery Health

–Start the Lenovo Settings program and click Power.
