Here’s an image of the component ID and wiring pertaining to the switch

Maybe check if there is a component marked UE2 on the board.

Looking at p.48 where LID_SW_IN# goes to, it goes from the sensor to the fingerprint board ''and also to the motherboard IO chipset'' (southbridge/northbridge - I always get confused)

Perhaps check the resistor and capacitor as shown in the image. This is if it is wired the same on your board, but it seems a reasonable assumption

I couldn’t see it too well on the image of the part linked above but my eyes aren’t what they were. If you traced the wiring from pin 3 of the fingerprint board connector you should find it.

Hi @flannelist ,
What is the board number of the motherboard?
