Problems Turning the Computer On?
Nothing happened when you pressed the Power button.
m The battery may be drained. Make sure that you plugged in the power adapter, and that
the power adapter is firmly connected to both the computer and a power source. If the
power adapter is plugged into a power strip, make sure the power strip is plugged in and
turned on.
m If the computer doesn’t start up when you press the Power button, hold down the Shift,
Function ( fn), and Control (ctrl) keys and then press the Power button (®). The Sleep
indicator light glows briefly while the computer goes through a reset process. After the
power indicator light turns off, wait a few seconds and then press the Power button again
to start up the computer. Once the battery has charged, you should be able to use the
Power button normally.
m If the computer still doesn’t turn on, see the troubleshooting manual that came with your
computer.
There is a slight delay after you press the power button before the computer
starts up.
m Every time you press the power button, the PowerBook performs a check of the
computer’s memory, causing a slight delay in startup. The more memory you have
installed in the PowerBook, the longer the delay.
You see a picture of a disk with a blinking question mark on the screen.
m This icon usually means that the computer can’t find system software on the hard disk or
any disks attached to the computer. You may need to reinstall system software. See the
troubleshooting manual that came with your computer.
