If your screen looks like the one below, with a small, labeled picture (icon) at the top right, then your computer is ready to use. Look at “Safety Instructions,” later in this book, for important safety instructions.

SImportant: If your screen looks like the one below, system software has already been installed. You don’t need to install system software. Do not use the Install Me First floppy disk or CD. S

If the screen is dark or you see a blinking question mark on the screen, refer to the next section, “Problems Starting Up.”

Problems starting up?

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

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

mIs 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.

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

mIf 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,” later in this book. Then turn on the external hard disk before you turn on your computer.
