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.
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
Move your pointer to the battery-status icon in the Windows notification area to check the battery status.
The battery-status icon displays the percentage of battery power remaining and how long you can use
your computer before you must charge the battery.
The rate at which you use battery power determines how long you can use the batteries 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 storage drive.
– How bright you make the computer display.
– How often you use the wireless features.
Using the ac power
The power to run your computer can come either from the battery or from ac power. While you use ac
power, the batteries charge automatically.
Your computer comes with an ac power adapter and a power cord.
