Different adapter on laptop

[fajarpn]

Hello
Right now i am using a different adapter for my laptop. The voltage is same with higher watt (s), but there are 2 different things:
-the original adapter is an AC adapter while what i am using now is an AC DC adapter
-the polarity of the adapter i am using now is unknown (original is 120p or so)
Will it break my laptop if i continue using this adapter?

Both adapters convert AC to DC, or they wouldn't work with your laptop. The polarity of the adapter you are using now is apparently the same as the old one, or your laptop wouldn't work using it. Something would likely fry if the polarity were reversed. And I have no idea what "p120" means.
