Problems starting up?

If you don’t see anything on the screen, check these items to see if you can identify the problem:

nIs the computer firmly plugged into a power source? If it is plugged into a power strip, is the power strip turned on?

nIs the computer itself turned on? Check to see if the power-on light on the front of your computer is green. If it’s not, you need to turn the computer on, using the main power switch at the back of the computer.

nIs the keyboard cable connected correctly? (Don’t disconnect the keyboard cable while your computer is on. You could damage your equipment.)

nIf you have an external hard disk attached to your computer, is that hard disk turned on? Was it turned on before you turned on the computer? If you’re not sure, turn everything off as described in “Turning the Computer On and Off.” Then turn on the external hard disk before you turn on your computer.

nIf you see a blinking question mark, you’ll need to install system software. Go to Chapter 8 of the Macintosh User’s Guide for instructions on installing system software from floppy disks. Make sure that the label of the Install Me First disk says it is for your Macintosh model.
