Apple Duo 270C Monitoring the battery charge level

Monitoring the battery charge level

The main battery provides power for up to 6 hours of work (the

exact time depends on how often you use the hard disk, how

bright the screen is, and other factors). Use the Battery desk

accessory to monitor the charge level of the battery so you can

recharge it when necessary.

Using the Battery desk accessory

To open the Battery desk accessory, choose Battery from the

Apple menu.

The Battery desk accessory appears.

The line of rectangles is the battery gauge. Black rectangles

indicate the charge level. You can see the level decrease while the

battery is in use, and increase while the battery is recharging in

the computer.

A lightning bolt icon appears when the power adapter is plugged

in and the battery is recharging in the computer. The lightning

bolt icon disappears when the battery is fully charged.
