Switch Power on From Good Battery, No Charge

Nintendo Questions
1

I have a Nintendo Switch that will not charge I only get 5V @ 0a. Plugging in a known charged battery the system is able to power on without issue and work as intended. However, when the system is powered on and plugged in with the good battery, the charging voltage drops to 1-2V which is very abnomral. Any ideas what it could be?

Didn’t measure any shorts by P13, M92 or BQ

0 amps indicates a blown fuse. Check the fuse on the vcc over the usb c port.

Sometime could be the 2R2 big inductor broken as well but rare :sweat_smile:
