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.
Checking battery status
The battery 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. For example:
How often you access the hard disk 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: Open the Power Manager program and click the Battery tab.
For Windows 8: Open the Lenovo Support program and click Battery Health, or open the Lenovo
Settings program and click Power.
Using the ac power adapter
The power to run your computer can come either from the lithium-ion (Li-ion) battery pack, or from ac power
through the ac power adapter. While you use ac power, the battery charges automatically.
