Ac Adapter Input Does It Matter?

YES!!!! It does matter, the current, voltage and power can cause your battery laptop to blow or the laptop itself to break; however, the new charger has a difference of 2.4 Amps, which is higher than the old one, it should be good, but at the long run it might break some Resistance inside the laptop, so be careful. I think you should buy one just like the old one.
