Is the way the dual mosfet work is if there was something wrong with the circuit that it would sink it to ground thus protecting the circuit? So when I remove the mosfet and I checked each leg and none had a direct short to ground. I checked my earlier pictures , although kinda hard to see I don't see the missing resistor.
What do you mean proper GND for my PSU ? My bench power supply is plugged into a power strip, and that is into outlet. None of the ground pins are broken off. I'll look around to see if anyone has picture of the motherboard area....Leave a comment:

Quick question. Is there way to check if the southbridge chip/PCH is gone, like checking the caps on the chip die itself? I have replaced all the components that I took off that was bad and now when I put 5v 1amp limit voltage on the input fuse where the 19v comes in from ac adapter it takes the full 1 amp draw. The dual mosfet with the arrow in the pic is one that is causing the amp draw, but when I removed it and applied the volt to individual pads it dose not take 1amp draw/ barely any draw. Its not the mosfet as I put a new part and got same result....Leave a comment:

Can you take a pic of the area? Really odd that there is no track there....Leave a comment:

Where in the ribbon cable is it broken ? if it is where the bend is then you can repair it with [B]enameled wire[/B] and put solder mask on top to protect it.Where in the ribbon cable is it broken ? if it is where the bend is then you can repair it with [B]enameled wire[/B] and put solder mask on top to protect it.Where in the ribbon cable is it broken ? if it is where the bend is then you can repair it with [B]enameled wire[/B] and put solder mask on top to protect it.Leave a comment:

Here is list of sellers overseas selling the mosfet, I didn't see any on aliexpress or ebay.

Also mention what model/motherboard version the switch will help also as this is not original version as there is no component like that there on the board. It looks like the connector that got toasted has damaged pin ?Leave a comment:

Here is another possible one but I'm leaning towards the first one.

This might be a possible one, ask the guys at digikey for verification, also take a better picture of it in circuit could help.Leave a comment:

First step is clean up the area with isoprop alcohol including desoldering the remainder of the damage power button. Then very light scrape away where you have white arrow (B) the black paint to see if there is a track going to where the pad used to be. Go very slow and clean the area in between steps. There should be a track there. Don't scrap hard because its mutilayer board.Leave a comment:

Here is the datasheet for the chip on your power supply, there is schematic but unfortunately no values were on there...

Are you asking for the one you marked in red arrow ? as i think it is actually C101 not c102 . I have not worked on the xbox but will try to look.Leave a comment:

have you tried taking off the same component nearby and testing in component tester ? which switch model is this ? did check at the shield corners/under ?
I haven't messed with wifi chip and don't know the part number.
Perhaps see if they have it here: [url]https://usoldering.com/switch-lite/[/url]https://have you tried taking off th... have it here:Leave a comment:

OK. I'll keep looking around the board while I wait for the parts. Link is good now and subscribed to your channel....Leave a comment:

is the pdf itself blurry to read? might have to contact Paul Daniels website and ask them that.Leave a comment:

I do believe i was getting 19v there when the laptop was working with one bad memory module slot. I measure what kind of volt on the other spots where i got my readings and that where i got the 19v , 5v , 3v and 1v . But yeah i understand why thats the power supply for pch vcore , like all the caps by the gpu and cpu v cores.
I did some more digging and a few more chips were bad - Parade PS8461E (diplay) , P13DPX (display mux switch). I order these chips and will get here in few weeks from China.
Resistance read red on gnd
19v - 3.4k and climb slow
