System Beep Codes
If an error that cannot be reported on the screen occurs during POST, the system may emit a series
of beeps that identifies the problem.
NOTE: If the system boots without a keyboard, mouse, or monitor attached, the system does not issue
beep codes related to those peripherals.
If a beep code is emitted, write down the series of beeps and then look it up in Table 2-4. If you are
unable to resolve the problem by looking up the meaning of the beep code, use system diagnostics
to identify the possible cause. If you are still unable to resolve the problem, see "Getting Help."
