    Friend has a laptop that is having charging issues. I was wondering if I could use my 90watt supply for their 65watt. I am just trying to isolate the problem, nothing long term. Thanks

    If the charger's output voltage is correct for your friend's laptop then yes you can use it.

    Edit : the plug will have to fit into the laptop properly too of course !

    Dell 19v at a guess.
    As Allan says, though you may get a warning message if it is Dell.

    Yes Dell 19.5V but the other is a HP (65W) 18.5V.

    Not recommended across manufacturers but should be within tolerance. (at your risk).

    I guess that is why my universal power plug is 19V?
