MacBook not turning on and no charger indication

Hi all, I have a MacBook Air (Model A1466 EMC 2925) that is completely unresponsive regardless of whether it is plugged in or not. The power button does nothing and when plugging in a charger there is no LED charging indicator. I have Cleaned the charger and port as well as plugging the charger into another macbook where it worked as normal. I have removed and replugged the battery as well as attempting an SMC reset (although I’m not sure the SMC reset worked). I have also done a voltage check on the battery I/O pins and pins 1&4 as well as pins 2&4 both have around 2.5V however the the battery is supposed to have a 7.6V output. Is there a way to test the battery pins to discern whether the problem is with the battery or not, a way to test the charger to battery continuity or anything else I can try?

Answer this question I have this problem too

Is this a good question?

It’s possible your I/O board is borked or something on your logic board.

I like Louis Rossmann’s videos about this:
