i would for sanity try to replace all gpu mosfets. Maybey it wil solve the problem . How much voltage is your main power rail and your dcin connector.

Good Idea, that would be my next step after reinforcing mosfet joints.

if you suspect a partial failed buck converter, the unwritten rule is to not just replace the Mosfets, but also every other related semiconductor, like drivers and the PWM controller of course, because they tend to damage each other.

Thank you. I usualy do that, even if it is just one failed power mosfet.
But lets hope it is just a contact problem because otherwise it takes 14 day to get mosfet and controller for me.

Hmm I have measured that PQ9002 and PQ9005 High side gates are in ohms range.
- PQ9002 High side resistance to ground is 900 Ohms
- PQ9005 High side resistance to ground is 55 Ohms
- PQ9006 High side resistance to ground is 11,5 KOhms
- PQ9001 High side resistance to ground is 11,5 KOhms

For me it seems that PQ9002 and PQ9005 are faulty as well, but I think I replace PU9002 and PU9003 controllers as well.
These are uP1909QDN8 and i got the info about the exact board schematic here:

Your measurements are irrelevant to asset the condition of the fet, It's not at all the proper way to measure it, you must measure resistance (or voltage drop) across S-G-D (S-D, D-S, S-G, D-G) of the fet itself (better out of circuit).
BTW the link in your post is broken.

Gate to source is 0 Ohm and since i dont have ESR meter, I have to remove them one by one to know the faulty ones.

Well 0 Ohm G to S is another story, definitely such a fet is defective if you're sure you measure it properly.

I remove all of them and get back with the measurements out of circuit.

The measurements of the Mosfets are inconclusive since you have measured Dual-Mosfets without mentioning and this way probably without realising.

I have known those are dual mosfets, Every second chip is in pair in these, so i can measure mosfets from their pair pads because they are empty.

The only thing that is strange, that after I have restarted the power and shut it down properly and then removed all power again, then the all mosfets high gates values are changed to 1,5 ohm.

Re: HP Omen 17t-w200 WHAE error when charger connected

I have Ordered 5 pack of Mosfets and 5 pack of controllers.
To be continued in 2 weeks when they arrived, or sooner if someone has better idea

SOLUTION:
After eliminating every hardware issue i decided to not change any mosfet since they not produce error on heavy load if nvidia is turned on after windows already started.
I have cleaned the BIOS ME region with the official HP BIOS upgrading software. and then booted windows 10 install usb in UEFI mode.
After the windows installer is installed windows without a problem and I have booted in UEFI from SSD also i knew that the problem is solved.
No errors or blue screens eversince.

Problem is back, I'm crying
The only thing that happened since it was working was that I take apart the heatsink because one of the heatpad does not contacted, So I have replaced the heatpad to a thicker one.

PROBLEM FINALLY SOLVED:
The culcpit of the problem was the Realtek Gigabit Ethernet Controller driver.
I was also surprised but after investigating the device HardwareID-s I narrowed down the problem to one PCI-E controller A151.
Maybe some of you ask: Why it was that disabling the NVIDIA card solved the problem. Later I found that when wrong driver is installed then the PCI-e A151 was used by the Network card and so the 2 devices interfered.
After the official driver was installed to the LAN device, the problem was finally gone.
Thanks for everyone that helped in the way.

MORE INFO: After a Few days, the problem always came back until finally the consequence is risen.

The restart only freezes if previously the laptop is heated up above 55-60 Celsius.
If I wait until it cools down in windows the it restarts fine.
I personally think this is a very bad hardware design since I can run any stress test inside windows once it is booted up.

[questore]

After thorough systematic tests the followings facts are sure:
1. Windows boot failes if the power adapter plugged in for a certain amount of time. About after 5 minutes (With or without battery connected it does not matter)
2. If I do a cold PowerON. The power adapter is not plugged in for half an hour and then I plug it in and start the computer, then it boots correctly.

I start diagnosing the charger circuit with a thermal camera, And checking the components around the charger IC.
Anybody has better idea?

[questore]

3. If I disable the NVIDIA GPU and restart the laptop, then reboot is OK then enable NVIDIA GPU and it runs OK
4. NVIDIA GPU is stable even on 118% power draw boost mode durring a 2hour stress test.
5. CPU stress test runs without problem.
+ charger circuit seem to work fine, If laptop is turned off and after the battery is full then nothing gets hot on the board.


HELP I'M OUT OF IDEAS

[questore]

After another project I have that have a wrong contac charger ID pin and did something similar freeze, I have checked every component on ID pin circuit.
I have 1.7V on te AD_ID pin when connected AC. It that good value for a 230watt charger? I found that D5100 i having Diode values 0.7V in one direction and 1.2V in the other way (multimeter in diode mode).
Should I check this Diode out of circuit to see its faulty?

Other strange thingaboth this.if I remove the AD_ID connector, then the same behaviour happens as normaly. No message that charger is low wattage or anything

(It even more suspicious that Schematic says that "Change to 1SS355 as Current loss" )

[questore]

I have managed to get a genuine 150Watt HP charger and AD_ID is 1.0v. This means that 1.7v might be OK for 240W charger ID pin.
Another thing that is a conclusion is that if you plug in a charger that is lower than expected, then the laptop simply not reacts to power button. (150W < 200W as expected)

BUT this does not explain why nothing bad happens when I NOT plug in the AD_ID connector, only the simple charger connector. In this case te AD_ID is 0V and laptop starts normaly.
Anyone knows this?
