    Hi,
    I bought a 180w universal notebook adapter for my laptop that uses 120w(20v 6a).So i thought 180w are more than enough but i noticed that only 100w of these 180 are being used in 2 ways.
    1: 19v 5.26a
    2: 16v 6.25a
    How can i use at least 120w

    If your points 1 & 2 are the universal adaptor's maximum output, then you return it as it is not capable of supplying enough voltage and amperage to your system.

    You need an adaptor which matches the voltage required by your notebook but is also capable of supplying the necessary current OR MORE.

    The voltage is very critical to match to your system's requirements. The amperage is not as important if the minimum is equal to or more, at the desired voltage.

    More information could help us, but the above should be enough for you to see if you need to return the current 180W adaptor and buy one that is better matched to your system's requirements.

    Good luck.

    Both those ratings point to it being a 100W adaptor, not 180W.

    180W at 19V would supply 9.48A

    Do you have a link to the adapter in question? Is there a way to manually switch between 19v and 16v modes?

    Running something GPU and CPU intensive while your laptop battery is charging would put out more watts, but 180W should be more than enough. Are you using one of those Save-A-Watt devices to measure the actual watts consumed?
