Error Messages
Your computer’s built-in memory (ROM) contains a series of
diagnostic programs, called power-on diagnostics. These
programs check various internal devices every time you turn
on the computer. The RAM test displays a count of the memory
currently installed in your system.
If the computer finds an error, it may display an error message
on the screen or sound an error tone code that identifies the
error, such as one beep-two beeps-one beep. If the error is
serious, the computer cancels further checking. The computer
locks up, and if there is an error message, it remains on the
screen. Write down the error message or the tone code pattern
and give it to your dealer when reporting a problem.
The tables below list the error messages and tone codes.
