I will put the plug the charger into the Nintendo switch and the charging symbol at the top of the screen won’t appear what does this mean and what do I do to fix this problem.
replace the M92T36 chip on the board or find somebody who can offer this service this should fix the issue if it is not a damaged charging port
Could be bad port, M9 chip, BQ chip, fuel guage chip, fuse.
