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."
