Hi:

 

See the service manual, chapter 8 pages 94 - 95 for how to do that.

 

Maintenance and Service Guide HP ProDesk 400 G4 Small Form Factor (SFF)

 

If removing the password jumper does not clear the password, then someone set the stringent security setting in the BIOS, which prevents removing the jumper from clearing the password.

 

There would be no way around that other than to replace the motherboard with one that doesn't have a BIOS P/W.
