So I was opening my laptop to replace the hard drive and I noticed something very strange. There was a loose wire. Do I need to be worried about this?

I posted earlier on Stackexchance electronics, but they closed the question saying it was the wrong forum. However, I got some info that this may have to do with my wireless card. I actually had been having strange problems with my wireless, such as it not working until I flipped on and off the physical wireless switch on the computer. However, when I upgraded to Windows 7 from Windows Vista, these problems disappeared.

Attached are some images. Thanks! enter image description here

I agree with @Moab, nice pics. I embedded them for you. – Raystafarian Mar 2 '12 at 18:34

Some wireless cards have a third antenna connection. This appears to be for that. The flat connector should be the same as the ones on the Wireless card in your image. Some use this for a Bluetooth card or something like a 3G or similar card. It just may be for an option that is not installed on your particular laptop.

Since the bare connector is loose, I'd make sure to at least cover the exposed metal with electrical tape prior to sealing up the system. – Blackbeagle Mar 1 '12 at 20:28
    
Cool, I guess I don't need to worry about it then. Thanks! – Amil Mar 4 '12 at 2:55
