Re: Dell XPS 13 9360 No charge

Do you have any dell donor boards,if so what motherboard part numbers are they.

Re: Dell XPS 13 9360 No charge

i got:
QALA1 (from Dell E6530)
QAL81 (from Dell E6430)
FX3MC (from Inspiron 15)
and several from very old Latitude D520 but i don't think they got anything like this.

Re: Dell XPS 13 9360 No charge

None of those will do. I found some on ali ,if you can wait a few weeks for delivery https://www.aliexpress.com/item/4000861764202.html

Good, thank you very much for everything!

Re: Dell XPS 13 9360 No charge

This seems to be a common problem on XPS13/15 series. I got the same problem, is this the affected part?

Re: Dell XPS 13 9360 No charge

Yes exactly!

Re: Dell XPS 13 9360 No charge

what soldering tip and temperature is needed for this? i never did any SMD soldering and need practice

got an old ERSA MS8000 soldering station

Re: Dell XPS 13 9360 No charge

Yes exactly!

These TVS diodes have been a problem for me too.Anyway i`ve found a TVS cross reference at baidu and copied the part i could see to a jpeg.

https://wenku.baidu.com/view/24ae99f...2396893e2.html

If the cross reference is accurate then it lists parts from semtech,protek,NXP and vishay.You can find the datasheets and see for yourself if you think one of them will be ok as a replacement. Some of those sites have a cross reference search (xref) so you can further xref each part number.
Edit: Found an older xref pdf from valorstat semi, it lists these 3 uClamp0501H, PESD5V0L1UB, AZ5125-01H

PESD5V0L1UB toshiba xref: https://toshiba.semicon-storage.com/...SD5V0L1UB.html

Re: Dell XPS 13 9360 No charge

Sorry to jump on an old thread here, but I have come across a very similar issue with a small twist. The TVS diode, PD102, and burned one side of the trace. See pic below. I did find what I think is a compatible donor from a Dell XPS 9560 board, 2nd pic. From what's left of the trace, it appears that it went to both the resistor marked #1 and cap marked #2. So ISTM I could attach a new tvs diode connecting to what's left of the trace at #2 and run a small jump from there to #1, is that right?

As usual thanks for your suggestions.

Re: Dell XPS 13 9360 No charge

Seems right to me, take a look at schematics to be 100% sure.

Re: Dell XPS 13 9360 No charge

burned one side of the trace. See pic below.

To me that looks like some residue/gunk/whatever. Is that really burned? Did you try cleaning it with IPA or nail polish remover (careful of course)?

Hi,i bought a xps9350 and i have the same problem
Is not charging the battery with dc Dell charger but is charging with usb c charger
I checked the PD102 and seems to be ok
PR103 also is good 33ohm
i do have 3,3v also on PQ101
So what ele can be?
I supose is not the BQ chip as log is charging with usb c charger

Confirm if the bios reports the correct stats of the attached power adapter.

Is the power adapter of the proper ratings for this logic board?

[nickstyle]

The bios says unknown power adapter. I do use a 45W Dell adapter.

[mon2]

Measure the voltage to ground of each pin on pq100. Post each measurement.

[nickstyle]

I have attached a pic with voltages
So i have 5,3.3 and 3.3V
Thank you

[mon2]

These are good voltage measurements. The gate voltage is higher than source / drain voltage so mosfet should be enabled to pass through the single wire communication traffic.

Remove all power. Meter in diode mode. Short the meter probes and the meter should tone beep. Touch one probe to one of the mosfet pins at 3v3 in the last measurement. No power to the board. Touch other meter probe to the dc adapter connector on the logic board used for the PSID. Do you hear a tone beep? If not, test the other mosfet pin.

This is to confirm the fault is not in the power adapter connector. One combination must tone beep. If yes, consider to remove this same mosfet and bypass the source and drain pins with a short with a wire or solder blob. There should be empty pcb pads for this bypass but remove the mosfet if testing this way.

This bypass is to rule out the mosfet as being defective. Many cases on this forum that confirm the mosfet as being defective.

Sorry for the trouble, it was the stupid power adapter. I ordered another adapter and is charging . The first 1 bought is second hand as i wanted to buy an original Dell

Hello my name is Paul I'm new to all of this but learning daily I've got same problem but it looks like I've got a hole in the little black resister right behind the port cloud this be my problem
