Nintendo Switch not charging, USB-C port, BQ24193 or M92T36 chip?

My guess would be a faulty USB-C connector, since I had a similar problem. The part only costs about $6 on eBay, but it's pretty tricky to replace (see YouTube).

Yeah, that sounds about right.

Thanks for your time reading and answering my post.

Last time it booted, the console showed 30% of battery charge.

I don´t know if the reading was correct.

In that time the battery level decresed normally and was shown in the screen.

This happened after i disconected the battery and pressed the power button a few seconds to completely discharge the motherboard.

I managed to turn it on and off many times, and everything seemed to work fine except the charger was not detected at all when conected to the usbc port (docked or directly).

The next day it wouldn´t power on, like when the battery is competely depleted. No battery signal, no attempt to start the screen whatsoever.

Yes, i tought so too. I already ordered a new usbc port and a M92T36 IC.

Those are my best bet.

In my case, some pasive components like resistors and capacitors were off value, so replacing those did the job.

My switch now works fine and charges normally. The only side effect i found is that the processor wont turn off completely, even after the OS is shutdown, it still heats and consume battery, so i have to keep it suspended.

This is problem of the M92T36 that is failing in the power off sequence, so i guess the definitive solution would be changing the IC, but for the time it will do as it is.

Hello Nahuel,

Which resistors and capacitors were off value specifically?

Thanks

You should check all of them one by one from the usb port to the BM92T36

There is no datasheet for the T36, but this one is pretty similar so you can check the correct volages the IC should be recieving from the power supply:

Here you´ll also can find usefull information about test pads on the board:

You should start from cluster K on this schematic:

Where can I buy the BM92T36. My switch is suffering the same problem it dosnt charge or power on anymore

Aliexpress is a good place to find this IC

Ok thanks I will check it out. An does your switch still work. My dosent charge or anything even when I put it into the dock the light dosnt blink green anymore. I check the USB slot and all the copper wire is ok nothing poking out or bent. My switch isn't even a year old and was brand new when I bought it. So for it to be doing this is mind boggling.

Also I'm not finding the BM92T36 on the website. I am however finding the BQ24193 is this the same thing?

Unfortunately, it seems that this is only a temporary fix, as the issue has reappeared. I'll try to find another dock + AC adapter to do further testing.

It turns out that neither the dock nor the AC adapter were faulty, since they both worked fine with another Switch. My original Switch had a faulty USB-C port, which wouldn't connect properly to the cable unless I would wiggle the cable around, hoping for the connection to be made.

It'll be great if you could upload images along with a brief description of the steps you've taken to solve it.

In my case I'll try to change the M92T36 first this weekend, and see how it goes.

You must really trust in your solder skills, three interventions on the same board seems very risky. Hope it'll work, it comes to a point when ordering pieces and replacing them is not worth it, unless you're doing it just to prove it can be done haha

Could you repair it with the BQ24193? I just tried changing M92T36 replacement with no success. Mine is not charging and also is stuck in nintendo switch logo.

None of those fixes worked, sorry about the lack of an update. In the end I wasn't able to to fix it, and then I gave the switch over to someone who said they can try fixing it and now I think I got scammed and he hasn't replied in months. The only fix I feel is what I saw another person on ifixit do with the same issue, they changed the resistor values or something like that.

It's a zero Ohm resistor.
