Edge 810 Internal photos

In the above photo does anyone know what the small round white component with the hole in the centre is? its at the bottom right of the photo, just down and left of the text 'UT 0020'.

I bought a second hand 810 from ebay that the original owner couldn't get to charge any more. I took it apart to see if I could swap the usb port easily, anyway it turns out it just needed a squirt of switch cleaner.

The round component fell out when I opened it. Now that I have cleaned the usb port it all seems to work fine, I have recorded a ride today without any problems and its synced to Garmin connect. The only thing that is maybe not working is the beeper, but this seems to be located under the battery.

If anyone does know what it is, would it be worth me trying to solder it back on? or can I live without it?
