Hey all,
Trying to fix a switch lite with a weird issue. Wondering if you’ve seen this before?
When I initially plug in the charger, it will draw 0.4 A and I get the battery icon. However, after a 5-10 secs screen goes black and my amp meter shows 0V / 0A. Basically the amp meter goes black like the switch shorted it.
If I disconnect the battery and reattach, the same sequence repeats.
I checked the usbc port using a breakout board and diode values are good.
No shorts around M92 or BQ but replaced both with no change to the behaviour. Tried a different shell and battery but also no change.
Thinking it might be the fuel gauge but diode values around the components all measure good.
What do you think?
