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. Report
any error messages when you request technical assistance.
The following table lists all the error messages that may appear
during power-on diagnostics. If you receive an error message,
look it up in the table below; it directs you to the proper
troubleshooting section in this chapter or offers a solution. If
you do not see an error message, read the section that covers
your problem.
