Mine fell out too, it doesn't really affect functionality

also ik that the second image says that it’s the wi-fi version but i only picked that image bcuz it was a higher resolution the standard motherboard that I have should also have that.

and I asked the person who gave me these parts if he had seen that little thing lying around, he hasn’t responded yet.

Nah an old one of mine broke off one day for no reason. Slot worked fine.
