Diagnostic Beep Codes - Dell Vostro 1540 Owner's Manual

Diagnostic Beep Codes

The computer may emit a series of beeps during start-up if the display cannot show
errors or problems. These series of beeps, called beep codes, identify various problems.
The delay between each beep is 300 ms, the delay between each set of beeps is 3
seconds, and the beep sound lasts 300 ms. After each beep and each set of beeps, the
BIOS should detect if the user presses the power button. If so, BIOS will jump out from
looping and execute the normal shutdown process and power system.
