Lid sensor not working properly

Hi,

If the magnets are in place, did you check directly opposite the magnets if the sensor is there? It shouldn't be too far away from being directly opposite to where the magnets are. With the laptop turned on and with the lid open run a magnet over the area where you think the sensor should be and check if the screen turns off -i.e. simulates the lid closed. If the screen turns off you're close to the sensor. Hopefully it will be working long enough for you to find it if you have to tap to make it work.

I can't find a free schematic download online but IF you have a Lenovo IdeaPad Flex 5 14ARE05 and IF the motherboard model number is FLMA0 LA-J710P then here's a link to a supplier that you can buy it from.

The schematic won't show the location of the lid sensor but it will show you the component on the schematic drawing along with its component type details etc.

If you can't find the sensor by what is printed on the sensor itself as shown by the schematics then you should be able to track down where it is by seeing what other component it connects to and tracing back from it.

Just what I'd try.
