System Beep Codes
When an error that cannot be reported on the monitor occurs during a boot routine, the system may emit a series of beeps that identifies the problem.
When a beep code is emitted, record it on a copy of the Diagnostics Checklist in " Getting Help ," and then look it up in Table 2 -11 . If you are unable to resolve
the problem by looking up the meaning of the beep code, use the system diagnostics to identify a more serious cause. If you are still unable to resolve the
problem, see "
Getting Help ."
NOTE: For the full name of an abbreviation or acronym used in this table, see " Abbreviations and Acronyms ."
NOTE: If the system boots without a keyboard, mouse, or monitor attached, the system will not issue beep codes related to those peripherals.
NOTE: Before you perform any procedures described in Table 2 -11 , see " Before You Begin " in "Troubleshooting Your System."
