Acer N35 Polarity

[Dazaal]

Excuse me if this is a very basic question but having bought the lite version of N35 with no Mains charger I have a generic one,does it matter what polarity I use & if so which?

yes of course,
i.e asus a636 is different polarity with acer althoug they have a 26p connector.
you can find every connector with its pins upside down too. watch out!
