Dell has a long tradition of building diagnostic indicators into our systems. These indicators can be really useful in helping to diagnose and resolve any issues your PC might experience whilst starting up. I've given a guide to the various codes for each family of notebook below.
If the display cannot show any errors your computer might emit a series of beeps during start-up.
3 means 3-3-3-3...That is 3 beeps and 3 beeps and ...: Endless looping until user presses the power button to shut down the system.
The delay between each beep is 300ms. The delay between each set of beeps is 3 sec, and the beep sound lasts 300ms.
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.
Please refer the below article for understand and troubleshooting dell beep sound.
