Processor speed
The reduced processor speed feature appears in the PowerBook control panel
if you have a PowerBook Duo 230. Reducing processor speed allows you to
slow the computer’s microprocessor speed (from 33 to 16 MHz). Some
programs may work more slowly, but you may gain up to 10–15 minutes of
work time before you need to recharge the battery. (The amount of time you
gain depends on how you are using the computer.)
To slow th e processor speed, follow these steps.

panel. (Or use the Power Settings module in the Control Strip to open the PowerBook
control panel.)

4Choose Restart from the Special menu.
