HP DV6 issue ?

Re: HP DV6 issue ?

I think the problem is after the power button is pushed, before the
other voltages we still control the voltages referred to the video chip, check PL37 1.8V_VGA as always in diode and resistance mode.

L37 Pin 1
Ohm 480 Ohm
Diode 0.23V

, Pin 2
Ohm 480 Ohm
Diode 0.23V

Where do we go after this ? thanks

Looks like the resistance is very low only 480 Ohm, remove L37 as well ?
Short on 1.8V,
So that VGA chip needs 1V and 1.8V ?

Thanks

What value for Ohm and diode on it to GND ? thanks

Any clues ???

Remove L37 ? Does it related with VGA chip as well ? thanks

Re: HP DV6 issue ?

I checked, there's a short on PL14, can it be removed ? thanks

looks like PQ65 is faulty, AON7702
