Re: NO POWER HP Pavilion Gaming 15-ec0013dx
Aright thanks for clarification.
I have my meter in ohms mode on the 200m setting. Lower settings (20m/200k/20k didn't show any reading.)
Top mosfet
Black probe on drain and red on source I get 1.1. Reverse probes it shows reading for 2 seconds as it climbs rapidly to OL. (15, 40, 80, 150)
Bottom mosfet

Re: NO POWER HP Pavilion Gaming 15-ec0013dx
Okay so this is new testing to me, but I think I understand.
Top mosfet with meter in diode mode
Red probe on source and black on drain is .668
Black probe on source and red on drain is open
Red probe on source and black on gate .478
Red probe on drain and black on gate its open, then if I put red probe back on source its opened (short to ground.)
Bottom mosfet with meter in diode mode
Red probe on source and black on drain is .668
Black probe on source...Leave a comment:

The 19v dc connector from charger is working correctly. Have 19v on the diode. I have continuity from the red side of the dc in to the back mosfets pictured....Leave a comment:

Not to sure where to measure. I typically do iphones only. Trying to expand. Thanks for help. Let me know if any of that helps. =)Leave a comment:

Yes, 0 ohms of resistance in diode mode. And I don't have schematics unfortunately.Leave a comment:

Re: NO POWER HP Pavilion Gaming 15-ec0013dx
No, all source pins 123 are short to ground. I don't think that's normal. I may be wrong though.Leave a comment:

NO POWER HP Pavilion Gaming 15-ec0013dx
NO POWER HP Pavilion Gaming 15-ec0013dx after prior attempt at battery replacement. Customer stated they slipped with a screw driver shorted a component out near battery connector and caused a spark.
Poked around with meter and found a short on the source legs on B20N03 mosfet (image attached). Mosfet looked a little burnt so I pulled but short remains on source. Looking for schematics or help further diagnosing.

a1708/820-00840 dead CPU?
I am new to mac repair, trying to drive right into some of my dead macs laying around.
I have a a1708/820-00840 board that pulled 20v/.02amps. Had a short to ground on PPBUS_G3H. Removed F7000 to confirm it was PBUS_G3H, which it was. Nothing looked bad so injected 12 volts into F7000 PBUS_G3H pad, which lit up Q7680. Pads P3V3S5_VSW were all short to ground so I removed L7690 which cleared those shorts but I am still short to ground on L7690 on pin 1. I am scared to inject this line with dcps beacuse it has lines to the U0500.
Thanks. -
