Error Messages

Your computer’s built-in memory (ROM) contains a series of diagnostic programs, called power-on diagnostics, which your computer runs automatically every time you turn it on. These programs check internal devices such as ROM, RAM, the timer, the keyboard controller, and the hard disk drive.

When the diagnostics test RAM, you see the total amount of memory currently installed in your system. If the computer finds an error, it displays an error message on the screen, Write down the error message and give it to the person who is helping you when you report the problem.

If the error is serious, the computer cancels further checking and halts system initialization. The error message remains on the screen and the computer locks up. If this happens, contact your Authorized Epson Servicer as soon as possible to report this information and the error message.

The Computer Won’t Start

If your computer does not start when you press the power button, try the following:

1.Check the power light. If it is on, the computer is on and you should follow the steps under “The LCD Screen is Blank later in this appendix. If the light is not on, go to step 2.

2.Press the power button to turn off the computer. If you are using the battery pack, remove it and reinstall it. If you are using the AC adapter, disconnect it and then reconnect it.

Then turn the power on again.

3.If the computer still does not start, the problem is probably caused by the power source; see “Battery Problems” or “AC Adapter Problems,” below.
