this switch wouldnt charge properly. 0.06 amps or so, but would display charging symbol. i replaced the m92t and bq ic and now the switch is charging properly with .4 amps, still showing charging symbol but isnt booting. usb port is ok. reesistances of usb port pins seems to be normal. couldnt find any shorts. any idea what the issue might be? thx
What voltage on the battery terminal? what does it do when you hold power button for 10sec?
You mean battery connector on the pins where the two red cable go?
without charger 4,05V-
with charger and battery connected 4.2V
with charger and battery not connected also 4.16v
holding powerbutton for 10 seconds gives me Nintendo logo for around 3 seconds.
