The first one at the top : the value goes up to 200 K and eventually shows OL then it continues and shows 1,500 M and the value goes down to show OL
the second below : the value is 0.569...

I carried out the measurements on the two mosfets in the photos above


--- Mosfet 1 ---

source (1-2-3) & drain (5-6-7-8) = 1.115 M
source (1-2-3) & gate (4) = 8.05 k
gate (4) & drain (5-6-7-8) = 0.900 M


--- Mosfet 2 ---

source (1-2-3) & drain (5-6-7-8) = 1.120 M
source (1-2-3) & gate (4) = 8.05 k
gate (4) & drain (5-6-7-8) = 1.108 M​

I have the impression that the DCin mosfets are on the other side of the card

--- Mosfet 1 ---

source (1-2-3) & drain (5-6-7-8) = 0.230
source (1-2-3) & gate (4) = 0.204
gate (4) & drain (5-6-7-8) = 0.437


--- Mosfet 2 ---

source (1-2-3) & drain (5-6-7-8) = starts at 0.80 and increase if I stay pressed until 0.250
source (1-2-3) & gate (4) = 0.219
gate (4) & drain (5-6-7-8) = 0.430​

Thanks for your help !

In resistance mode i select M because k gives OL. while M i have :

Meter probe onto the ACDRV pin on the charger IC and the other meter probe onto pin # 4 gives1.200 on the first Mosfet and 1,450 on the second Mosfet

For this test :

Yes i have fine tipped meter probes
the ACDRV pin with power gives me 24,8v

I will try to locate 4k smd resistor to find the 2 x DCin mosfets

If Mosfet is defective what value would i have with the multimeter ?

Thanks for your answer !

if I don't say something stupid PU8901 is charger IC

the first one I tried gives me an increasing value until 200
The second gives me 0.610

Hello,

I have an ASUS laptop that no longer turns on when I press the power button yet 3 lights are present when the charger is plugged in (power button, airplane mode and shift)

Thanks to the forum I got the diagrams. I took measurements with the multimeter but I can't identify the problem.

I have the impression that ALL_SYSTEM_PWRGD is the problem.

On leg 68 I measure 199.4 on the voltmeter​
