    Does anyone know what the 5790 uses?

    Most likely a 3-prong. That's what most notebooks use. I don't really know what the difference is between them, though (more power flows through?).

    I own a 5790, and it's a three-prong plug. From HowStuffWorks:

    " If you look around your house, what you will find is that just about every appliance with a metal case has a three-prong outlet. This may also include some things, like your computer, that have a metal-encased power supply inside even if the device itself comes in a plastic case. The idea behind grounding is to protect the people who use metal-encased appliances from electric shock. The casing is connected directly to the ground prong.

    Let's say that a wire comes loose inside an ungrounded metal case, and the loose wire touches the metal case. If the loose wire is hot, then the metal case is now hot, and anyone who touches it will get a potentially fatal shock. With the case grounded, the electricity from the hot wire flows straight to ground, and this trips the fuse in the fuse box. Now the appliance won't work, but it won't kill you either.    "

    Ah, neat. Kinda like a surge-protector?

    I would assume that this would only render the powerbrick, not the actual notebook, useless. Is this correct?

    Thanks for the replies! I bought a APC portable surge protector the other day, and I realized it was a three-prong version. I began to worry that the 5790 might use a two-prong plug and I'd have to return it (a real pain, I'd have to ship it back). Thankfully, this isn't the case!

    Thanks once again!

    Three prongs can be a bad thing. If you connect your computer to a coaxial cable, you might get a circuit because you'll have two grounds. This happened to my PS3 and it shocked me on numerous occasions. I have yet to hook up my notebook to cable so I can't say whether it will happen to you. The solution is to get a 3-to-2 prong adapter, eliminating one of the grounds. Of course, you should only use it when connected to a coaxial cable ;)
