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 allowing
you to take your work wherever you go. With ThinkPad batteries, you will be able to work longer without

• The way you use your computer: how often you access the hard disk drive; how bright you make the
computer display.
