Power Meter
The Windows Power Meter indicates the remaining battery charge. To check the Power Meter, double-
click the
icon on the taskbar.
If the computer is connected to an electrical outlet, a icon appears.
Charge Gauge
By pressing (or pressing and holding ) the status button on the charge gauge on the battery, you can check:
• Battery charge (check by pressing and releasing the status button)
• Battery health (check by pressing and holding the status button)
The battery operating time is largely determined by the number of times it is charged. After hundreds of
charge and discharge cycles, batteries lose some charge capacity—or battery health. That is, a battery can
show a status of "charged" but maintain a reduced charge capacity (health).
Check the Battery Charge
To check the battery charge, press the status button on the battery charge gauge to illuminate the charge-
level lights. Each light represents approximately 20 percent of the total battery charge. For example, if
the battery has 80 percent of its charge remaining, four of the lights are on. If no lights appear, the
battery has no charge.
