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.
I'm also looking for schematic or board view of this board.. encountered a problem 5 long 3 shorts, i already flash bios via keyboard PC run for several days and return to 5 blinks and 3 shorts. I tried replacing the memory, check and soldered ram slot pins - no luck, I also clear ME and flash bios and using CH431a programmer still no luck.
