The Diagnostic LED blinks red 4 times (once per second), then a 2-second pause follows, and then it beeps 4 times:
This indicates power failure.
Since we cannot locate a schematic, you will have to post pics of the board. You should start a fresh thread in the laptop forum regarding this laptop.
Then, review where the power adapter enters the logic board. In this area will be 2*DCin mosfets and the charger IC. The charger IC will be a black square device. We need to know the topside markings of the IC.
Often, HP will use charger ICs with 'BQ' markings from Texas Instruments.
