No it has not. Athlon 64s are made in Socket 754 and Socket 939
variants--just saying "Athlon(TM) 64" tells you nothing whatsoever about
the socket.

I read the site and it looked like a bunch of people whingeing. Searching
the page for "939" got no hits at all.

Further research indicates that apparently for some bizarre reason HP built
a laptop that cannot possibly use a mobile processor. I'd be more worried
about that than about whether it has the second memory channel enabled.
