1 Why isn't my Switch Lite charging?
Basically what the title says - I have replaced the battery in my son's Switch Lite, but to no avail. I really would love to be able to effectively diagnose and replace whatever part needs replacing. I have the means with which to solder and replace pieces on the PCB if that's what it comes to. I just don't know how to diagnose each specific part of charging a Nintendo Switch Lite. There are so many components on the MB and I have no way of knowing which ones to check. I have a multimeter, I have magnifying lenses, etc. Can anyone help me get started? I don't want to desolder the USB-C port if I don't have to. I'd rather start with diagnosing first and then replacing as a last resort. Any help is appreciated!
Info:
Was it not charging before you changed the battery, or was the battery just low capacity and you wanted to get a better battery?
Do you have access to another switch lite that can charge the battery?

@erelectronics Thanks for the comment! His battery was not charging before I changed the battery. Me replacing it was more of a way to weed out the battery as the culprit. I do not have access to another switch lite, sadly.

Ah. Understood. I am not sure how similar the Lite is to the Switch (I really only have experience with the regular). So take this generalized advice with a bit of salt and research more specific numbers for your system as they may be different:

This image shows the ratings on an official Switch charger, as well as pinout for positive and negative power pins (they only put this pinout diagram on regions that require it).
First check your charger and make sure it is outputting the correct power (voltage) on the correct pins.
Then check when plugged into the USB-C on the switch. If full and correct power is not getting to the board, the USB-C needs replacing.
Then check if power is getting to the charging IC (I know these give lots of problems on OG handhelds)(it will likely NOT be the full 5V/15V, as that will be altered by onboard chips and components). If power is not getting to the IC, likely a component in the middle is dead.

Diagnosing the charging IC and the video IC is next. There's a whole article I've referred to multiple times that breaks it down well: https://repair.wiki/w/Nintendo_Switch_No...
Key to remember is that even if you find, for example, the USB-C port is busted, it may still require more work after replacing that as often times components in these systems fail together.
All of this is assuming that the new battery you got was good and not DOA, which is possible but unlikely.
I know you said you have the equipment, but if you have never microsoldered before PLEASE practice on something else you don't mind destroying. It is not as easy as YouTube experts make it look and you WILL destroy something your first time trying.
(Again, my advice is based on experience with standard Switch consoles. I don't know how well any of this translates over to a Lite system, it depends on how much Nintendo changed between one and the other.)

@erelectronics Totally get it, and thank you so much for the information! I'll give this a shot and report back!
