    Use a higher rated adapter instead of a lower one or you'll likely experience performance hits or system shutdowns.

    I've personally tested a Dell 90W adapter on the M14x and used it under full load without any issues.

    This is a great way to kill your battery. High power will overcharge and severely shorten the life of your battery. Safer to go with less than more in this instance.

    If it is higher voltage or amperage then this is correct. Higher wattage will not. Wattage is how much power a power supply can make, that doesn't mean our M14x's will use all of it (or the PSU will "jam all the energy into it"). So say we find a 170W PSU for our 150W systems, we have 20W of padding that may actually help us with things like overclocking that take a system's power requirements beyond specification.

    Prime example; I have a 1000W PSU in my desktop when I probably only need about 500W. Hasn't hurt a thing in years.

    EDIT: I would imagine on the opposite end of the scale, getting an under rated PSU would probably cause the battery to not stay charged under load. Or, if you removed the battery, you'd probably experience system instability.

    tl;dr Never cheap out on a psu

    Not at all, the charger isn't 'pushing' power to your battery, it's the system that draws as much as it needs.

    @ PhAyzoN while you are mainly right, keep in mind that Watts = Amps x Volts

    higher or lower both not fit for your laptop,
    chose lower if there is no 150w,
    higher adapter might damage your computer

    Same goes for lower, it won't be able to provide enough.
    Before you start spreading things as if they were facts, please document yourselves first.
    Nothing will get broken or explode or whatever might cross your minds!

    You are correct. I forgot that's how it worked, it's been a while since I've learned such things and never really put that knowledge to use. :)

    So I believe having proper voltage is important (in terms of damaging electronics), but amperage can be greater?

    Yes, that's correct.
