Appendix B
Power-on Diagnostics
Your computer’s built-in memory (ROM) contains a series of
diagnostics programs, which your computer runs automatically
every time you turn on the power. These programs check
internal devices such as ROM, RAM, the timer, the keyboard
controller, and the hard disk drive. If the computer finds an
error, it displays a specific error number and error message on
the screen.
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 dealer as soon as possible. Report both the error message
and code number.
If the
error
is not serious, the computer waits for you to resume
further checking. You see this prompt:
(Resume = "F1" key)
Write down the error message and code number, and then press
F1 to continue. Report the error message and code number to
your dealer when requesting repairs.
The following table lists all the error codes and messages which
may appear during power-on diagnostics checks.
