Troubleshooting 91

If the computer won’t turn on or start up

m Make sure the power adapter is plugged into the computer and into a functioning

power outlet.

m Your battery may need to be recharged. Press the small button on the battery (see

page 55). You should see one to four lights indicating the battery’s level of charge.

m If that does not work, locate the reset button (see page 20) on the back panel of your

computer. Carefully press the button using the tip of a pen. Make sure the button

releases after you have pressed it.

Note: You may need to reset the date and time (using the Date & Time control panel in

Mac OS 9 or the Date & Time pane of System Preferences in Mac OS X) after you use the

reset button.

m If that does not work, press the Power button (®) and immediately hold down the

Command (x), Option, P, and R keys until you hear the startup sound a second time.

m If you recently installed additional memory, make sure that it is correctly installed and

that it is compatible with your computer. See whether removing it allows the computer to

start up.

m If you are still unable to start up your computer, see the service and support information

that came with your PowerBook for information on contacting Apple for service.
