Question
Hi,
I have a USB charger with the little wall charger connection thingy. When I plug it in the wall it charges and when I plug it in the laptop it says unauthorized charger. I have used USB cables for other phones on this laptop b4 with no problem.
Thank you
Some devices only allow certain chargers. It's very likely that the laptop needs a charger with more amps and that is why it can't use the charger. Just because the connection is USB doesn't mean it will work. If you look at the charger that came with the laptop and look at the charger you have, you will see that there is more voltage for the laptop charger and you need that amount of voltage on another charger to use it. Hope this helps.
