Default Nintendo Switch : Charging only in standby mode

Hello,

This Switch will eventually drive me crazy

It only switches to standby mode and refuses to take charge once it is on.

If I plug it in on, nothing happens until it goes into standby and there the charge is automatically triggered.

So I changed the charging connector, the P13USB, the M92 as well as the BQ which normally manages the battery charge without more success.

What do you think?

Here is a link from a video that show my problem : https://drive.google.com/file/d/1gqP...ew?usp=sharing

Thank you in advance and best wishes to all of you

Default Re: Nintendo Switch : Charging only in standby mode

I've heard mention of a fuel gauge IC that can cause issues when I was working on switches when I got started with this hobby. Don't know what that IC actually is so unfortunately I can't be of much more help there but hopefully it gives you something to research.
Edit: a quick Google search says it's the MAX17050 IC.
