First off I am surprised that the 'front grill' is even metal. That

contiguous connection, that it should connect to the LOW side of any
power (source) connection. Like DC(-) or AC(neu).
I do not have a lot of laptop experience. How does direct wall AC
interface with a laptop? I should think a wall-wort, or, some 2-pin
homogenized interface (uh-oh!)
Again, you have a really good one!
If I check from front grill to the VGA port, USB port, Firewire port,
or outside edge of the power jack on the laptop, the connection is
contiguous. If I try from the middle pin of the power jack to the
front grill, my multimeter drops from 100 to 70, which I read as a a
partial connection (some resistance.) All this seems strange to me,
because I would think the outside case of the laptop shouldn't be
connected directly to power for safety reasons. Of course, I may be
completely misunderstanding this.
