Troubleshooting with the e-buzzer
When your system starts up, the system firmware performs pre-boot diagnostics to test
your hardware configuration for any problems. If a problem is detected during pre-boot,
the system e-buzzer will emit audible beeps and an encoded error message.
The e-buzzer emits a different number of beeps for each type of error. The sequence may
start with a modem-like sound lasting about three seconds, followed by a number of clear
beeps, or the e-buzzer may simple emit clear beeps.
The e-buzzer detects the following errors after a 15-second timeout:
