Most probably, it interrupted the BIOS update.

Hi @decu2000 

 

 

HP Desktop PCs - Computer beeps or a light blinks during startup | HP® Support

The red light blinks twice, and then four, short white light blinks (2 long red, 4 short white)

This condition indicates that the embedded controller is checking or recovering the boot block.

  1. Allow the system to attempt to recover the BIOS.

  2. Attempt Sure Start Recovery if the issue persists after waiting several minutes.

Hi!

This happened just after plug the power adapter ( no need to push power button ).
The USB ports are not active.
