The Computer Won’t Start

If your computer does not start up when you turn on the power switch, follow the steps below. (If you have a hard disk, also see the section on hard disk problems later in this chapter.)

1.Check that the POWER light on the front panel of the main unit is on. If it is not, remove any diskettes you have in the drives and turn off the power. Wait five seconds, then turn the power back on.

2.If the light still does not come on, turn off the power again. Check that the power cord is securely connected to both the AC inlet on the back panel and an electrical outlet. Then turn the power back on.

3.If the computer still does not start up, check that your electrical outlet is working by plugging a lamp into the outlet and turning it on.

4.If the electrical outlet is working and all the connections are secure but your computer still won’t start, see your Epson dealer.

The Computer Locks Up

If the computer-does not respond to your keyboard entries, try the following:

1.Check the key lock to see if it is locked. If it is, the computer does not respond to anything you enter on the keyboard. Turn the key to the left to unlock it. (See Chapter 4 for more information on the key lock.)
