Problems turning on your computer?
m
The computer made a sound, but you can’t see anything on the screen.
Adjust the brightness control buttons until an image appears and the screen
is easy to read.

Nothing happened when you pressed the Power On key.
Make sure 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. Then try pressing the
Power On key again.
If you still get no results, press the power button on the back of the
computer.
If neither the Power On key nor the power button turns the computer on,
see the PowerBook Troubleshooting Guide you received with your computer
for help.
