HP Probook 440 G9 No Wifi

[titomno2]

Hello everyone,
Trying to fix a Laptop HP Probook 440 G9 with no wifi.
Motherboard is DA0X8SMB8H1 REV.H
Symptoms was the student could not shutoff the computer and when inspecting the computer I found the following component burned (SOT23).
Sorry can't find a boardview or schematic.
If anyone has any idea, I see at least 200 and maybe a 5 or 6 at the end (see pictures).



Thank you.

I have removed the SOT23-3 component, and made some measurement.
The bottom pin on picture is 3.3V.
The right pin on picture is somehow related to the 3.3V for the pcie ngff slot
So I assume the top pin is the gate.
I tried the 2N7002K as replacement but it seems that the wifi card is still not powered (I have tested the card somewhere else and it was performing normally).

Some of you may have some idea as I am still unable to find any schematic or picture of component I should put in place?

So the 2N7002K is not the optimal solution, it worked few minutes and then no more, it seems that the gate is not activated with enough power (3.3V on the source and only 2.5 to 2.8V at the drain).
So I decided a dodgy fix by replacing with a 0Ohms resistor between the drain and source (of course I loose the opportunity to go in plane mode) => it works well.
I have still an issue, the battery charging reaching 55W on the dc jack when computer is working, which is too much for the 45W adapter ! I don't know why it drain so much power (current sensor drift ?).

Fun fact or not I know what caused the SOT23-3 component to burn, a capacitor was shorted between 3.3V and ground on the pci e socket (a very small one).

I write all my way to solve this issue hoping it could help someone else.
