Replacing the cap
The cap 1 on the end of the TrackPoint pointing stick is removable. After you use the cap for a period
of time, you can replace the cap with a new one.
Note: The TrackPoint cap used in your computer has grooves 2 as shown in the following illustration.
Ensure that you replace the TrackPoint cap with a correct one that has such grooves.
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.
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 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 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: how often you access the hard disk drive or solid-state drive; how
bright you make the computer display.
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 Settings program and click Power .

The power to run your computer can come either from the lithium-ion (Li-ion) battery pack provided with it,
or from ac power through the ac power adapter.
The ac power adapter that comes with your computer has two basic components:
• The transformer pack that converts ac power for use with the computer.
