My Switch charges at .41, no shorted caps on MB, charge symbol green as charge is almost full, have to hold down power button for 12 second to get nintendo splash screen for 1 second then goes away. Also when plugging into charger it does not always display charge symbol. I am using official charger.
The chip which controls the charge if might be fried, did you have a thunder storm recently that could have done this? Another culprit it worn out soldering joints which need resoldered on.
