IMPORTANT

Lithium ion (LiIon) batteries contain metals that are hazardous

when released in the environment. It is inappropriate, and in some cases

unlawful, to throw batteries away with your household or business trash.

Many locations have government or Apple-sponsored collection or recycling

programs for spent batteries. Dispose of spent batteries in accordance with

the mandatory or voluntary battery collection programs in your location.

Contact your Apple-authorized service provider for information about the

recommended disposal procedures in your area.

Maximizing work time

Your Macintosh PowerBook’s battery can provide 2–4 hours of work time

before you need to recharge. The actual work time available depends on

which model of Macintosh PowerBook you have, what equipment you’re

using with your computer, and what steps you take to conserve power while

you work.

To save battery power, you can do the following:

m Minimize backlighting of the display.

m Turn off AppleTalk if your PowerBook is not connected to a network.

m Set the hard disk to spin down after a very short interval.

m Remove PC Cards when they are not in use.

m Take advantage of the sleep and wake features of your PowerBook

whenever your work is interrupted. You just need to close the display to

put the computer in sleep.

For more battery conservation tips, see the “Batteries & Power” topic area

of Mac OS Guide, available in the Guide (h) menu.
