    i am very confused.. having looked at laptops for awhile now i have seen many spec pages which do not include power supply specs.. is this because all laptops have the same power supply or are they like a desktops power supply and can be upgraded?

    I have given the Experts over an hour to chime in on this so now I will take a stab. Unlike desktop components that would require substantially different power draws notebook components that would require more draw (GPU) are not swappable. Why would you want to upgrade power supply?

    They have a built in power supply and are either 45w, 65w for most notebooks, but for 17" and larger, they can vary depending on model.

    Laptops have different voltages and watts, but it will have defiantly have enough power to power on your notebook and charge your battery at the same time.

    It is just not important to laptops because it is hard to upgrade components, and if you do, it will probably not use much more power than the previous one.

    Unlike desktops, there is no "upgrading" of the power supply. The one sent with a particular notebook is designed for the hardware it was installed with at the factory.

    Taking HP as an example, most units with integrated graphics get the 65W psu, while the dedicated ram/gpu models are usually spec'd for a 90W psu (as they require a tad more juice to run). It is more of a mainboard dependency with notebooks rather than a "peripheral" one like extra hard drives/fans/etc. (as it is in desktops).
