Hi

A single beep is rare on post 2015 machines, so what age and BIOS is it please.

Possibilities...

Caps/Num Lock LED / BEEPS

Component.

Error condition

Corrective action

LED blinks once.

CPU

CPU not functional

  1. Re-seat the processor. NB:- See the Services Media Library for steps for your PC.

  2. Replace the processor. NB:- See the Services Media Library for steps for your PC.

  3. If the CPU still does not function properly, replace the Main-Board.

LED blinks twice.

BIOS

BIOS corruption failure.

Reset the CMOS:

1 Restore BIOS if available. (If you can access the CMOS battery, pull it out and re-seat it.)

NB:- See the Services Media Library for steps for your PC.
2 Press the Windows + B keys to do a BIOS recovery.
If the error persists, replace the Main-Board.

 

1 long beep followed by 2 or 3 short beeps
