The return spring for the LCD cover latch on my m6500 has come out of place.  I found it next to the primary HHD.  It appears to work in a torsion configuration, but I don't see how exactly to install it.  Nothing seems to be broken in the latch mechanism itself, but without the spring, of course it does not function properly (hold the lid closed).  Any idea how to install this spring?  Thanks.
