Monitoring the battery charge level
Your computer’s main power source is a nickel-cadmium battery.
The battery provides power for up to 3 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
( K ) menu.
