Much apprciate our informative feedback, i'll be explore other part to try to find fault. thanks so much -
No the mesurement is from motherboar where i remouve mosfet
here mosfet mesurement i remouve
Calibre 600k
[B]source red prob / drain black prob= OL
source red prob / gate black prob = OL[/B]
[B]gate red prob / drain black prob = OL[/B]

After remouve Q6010 and let cool motherboard and take mesurement it same
mesurement take in motherboard:
[B]source / drain = 231k
source / gate = 150k
gate / drain = 513k[/B]
After fallowing topic to find defective mosfet, all different test q6010 like goodAfter remouve Q6010 and let cool motherboard and take mesurement it same

thank for reply
Test on [U][B]Q6010[/B][/U] in resistance mod:
[B]source / drain = 229k
source / gate = 150k
gate / drain = 512k[/B]
Measurement of the resistance to ground of pin # 1 on [U][B]U6000 [/B][/U](ACN) = [B]50k[/B]

HP Folio 9470m 6050A2514101-MB-A02.no Main Power
Hello everyone. I have on the table HP Folio 9470m with mobo [B]6050A2514101-MB-A02[/B]. Laptop has not power. No main power
19v present on source of Q6010
the gate have 19v
the drain have 0v
i test these mosfet (Q6009; Q6010) but it like good i think the probleme is Q6009 ADP_EN signal from KBC before replace KBC Controller i come here to find well the faulty compnnenent.

Acer Predator Helios 300, FH52M LA-J891P REV.1 A No Power
Mainboard ; FH52M LA-J891P REV:1 A
Hi everyone happy new year to all
I try to fix this motherboard no power missing 19v
the first DCIN PQB11 mosfet receiveide 19v in drain.
the test i have done :
Mosfet PQB11 and PQB12 check and change still have no power
Charging IC PUB1 check step:
-VCC pin 28 = 19V
-ACDET pin 6 =2,62V
-REGN pin 24 = 6V
-CMSRC pin 3 = 0V
At this step i replaced IC but still problem no voltage in gate on 2 dcin mosfet
What i missing?
the schematic in below
Thanks

Electronics components and ic
Hello everyone!!!,
I hope in dedicated topic,
I'm in the process of opening my own electronics repair store, and I need your help with a list of must-have components like ic, mosfet, smd diode resistor etc... for PC repair. and purchasing links will also be useful. thank everyone! -
