Error Messages
Your computer’s built-m memory (ROM) contains a series of
diagnostic programs, called power-on diagnostics. These
programs check internal devices such as ROM, RAM, the timer,
the keyboard controller, and the hard disk drive every time you
turn on the computer or press the reset button. The RAM test
program displays a count of the memory currently installed in
your system.
If the computer finds an error, it reports one of the following
types of error messages:
Power-on diagnostic and boot error messages
Error tone codes for fatal errors (that lock up the system)
Error tone codes for non-fatal errors (that do not lock up
the system).
Be sure to write down the error message or tone code pattern
and give the information to your dealer when you report a
