    can anybody say why some notebook manufacturers use two prong (Toshiba) and
    others use three prong (Compaq)?

    Compliance with the electrical regulations of target markets.

    No it is not a reason. It's only Compaq (and maybe some other firm) way to
    get a few extra $$$ from customers pocket.

    I think it's design choice. $$$ has nothing to do with it.

    Oh really? 2-prong cable You can buy from various manufacturer so the price
    is low (<1$). 3-prong cable costs 8$ 'cos only few firms is providing it. Do
    You see the diffrence?

  6. The three prong cables ARE more expensive, of course, but you cannot
    judge the cost of anything by the price that we pay when we buy one of
    them. Believe me, it's real different when you are HP or Compaq buying
    a million of them, with the ability to buy them anywhere in the world
    (China, Taiwan, Korea, etc.).

    Correct the difference is probably 10 cents vs 12 cents.

    It may be cheaper for them to stock just 1 cable for desktops and laptops.

    It could be many reasons they do this.

    I think the most important though is travel weight is higher for 3 prong.

    You can get 3 prongs anywhere. Are we talking about the same 3 prong. I have
    seen some laptops with the 2 prong (small round circles).
    3 prong (3 small circles) and the ones with the same cable you have on
    desktop pc's and monitors.

    Why they use the 3 prong (3 small circles) is strange. I think some dells do

    Although Dell has a cool adapter to make theirs a wall wart (no cable) and
    is good for travel weight and less clutter.
