essentially identical to a NEMA 1-15. However, both "bricks" that I have
use a 3-wire cord instead of a 2-wire like every other laptop I've
had/used

My Dell laptop PSU uses a 3-wire cord - but dismantling it revealed that
the ground isn't actually connected to anything internally. I've used
mine on US power with and without a ground, and UK power (230V @ 50Hz)
with no problems (but not Japan :-)

good to know. I'll just toss a cheater plug in my laptop bag then and
call it good. Primarily I am planning on taking it to watch DVDs on the
plane (I have an AC/DC brick with an auto/air cord as well as an AC
cord) but hey, if I'm going to cart it with me, might as well see if I
can check my email while I'm there too.

I don't really have any easy way to generate 100V/50Hz here at my house
but I can't imagine it wouldn't work?

FWIW my laptop (Precision M90) shipped with a 130W power supply but it
seems to be fat and happy here in the living room running off the 65W
supply I just got from eBay (that's the one with the auto/air cord. I
also tested it off a benchtop 12V power supply and it seems to be good
on that too.) I guess I just won't be doing any rendering or any
processor intensive stuff while I'm in the air

Now to remember to get on Project Gutenberg and download lots of books
to read too.
