monitor "pin" problems

Okay, so I'm not exactly sure what the correct terminology for this part is, but what I'm having problems with is the little 'pin' that sticks up near the power switch that allows your computer monitor to go blank when the computer is closed. Somehow it got stuck in, and it's not coming back up. The monitor stays on when it's closed now, and if I touch, or move the computer too much, the display sometimes blanks out as a result. It's strictly a hardware issue, though, as the computer works fine when the display works.

 

Any advice?

 

Thanks,
