extreme heat on back of screen?

[Brian <clarke_bp@virginia.edu>]

My 755C (got it used) tends to get extremely hot on the back left side
of the screen...does anyone know 1) why this occurs, 2) whether it's a
bad thing, and 3) if there's anything I can do about it?  I tried to
register it/get info on it at IBM's site, but it didn't recognize the
S/N.  I would assume it was part of a fleet that some company had leased
at some point, but regardless, I didn't get much in the way of useful
info so I'd really appreciate it if anyone could help me out...
