Nintendo switch no power,

So my Nintendo switch doesn’t turn on so far I’ve tried putting a fully charged battery in it and no difference also tried docking it but it blinks once and turns off if I leave it on charge it gets vary hot but still won’t turn on I was told it could be the m92t36 ic chip but I have my doubts if you read online the ones with the bad ic when docked have a rapid flashing dock led mind just flashes once

any input would be great
