Hi there,
I need some help to fix HP Omen 17, Quanta G37A laptop (no history, signs of "inspection") no power, AC LED off when the adapter is plugged-in.
Following piernov guide: with original HP power adapter, measured the voltages at DC_JACK and found +VDD =19.6V , AD_ID =0.60V.
Next, +VAD at drain of 2nd MOSFET (PQ1003) is 19.5V and 0V at source and drain! Resistance of source to ground 16.3 ohms!
Voltages at PU1001 (BQ24738): ACDET= 2.60V, REGN= 5.95V and VCC=19.0V, CMSRC=0V !
So, is it "short to ground on main power rail" case?
