Got a HAC CPU 20 v1 nintendo switch which i’ve been doing for a week now, unit is working as normal, it’s just it doeans’t charge, when i plus original charger, it shows a green charging icon, but battery level not going up, Hooked it up on a voltmeter, and its just shows just .5 amps compared to .43amps in a normal working switch. things ive already check.
Changed m9 power ic twice
changed bq ic once
changed fuel gauge once
no short on ground on components
tried a different battery doesnt make any difference
check usb type c continuity for each points all good
readings on power ic normal, 3.2v on pin 5,6 1.8v on small cap below
getting 15v on both sides of the fuse. voltage actually reaching m9 power ic.
anyone got an idea or same issue? just want to know where to look out next. just not familiar with this kind of issue on this switches. TIA
actually i already tried using other battery, just the same result, same hecate batt info shown, running out of ideas, already changed usb type port as well, and tested it after using a breakout board i bought from aliexpress, just changed my BQ ic again.
now the board is not powering on, no shorts, but just noticed something off, on the capacitors under the bQ24193 ic, i dont get any value in diode mode. compared to a working board, wondering if this is connected to a rail, coz i already tried replacing the bq ic and and the capacitors from a donor board, but still no reading.
my wall charger <> wire <> male usb typec port
→ when I cut the wire … there are 5 wires … I am trying to understand those wires … the multimeter is not helping … could u please help me … i want to know these 2 things:
a) how these 5 wires are connecting to the female usb typec port
b) I think the switch console needs 5volts “x” amps and the nintendo dock needs 15 volts “x” amps
