I can't find any information regarding the polarity of an ACER Aspire Notebook charger. I lost it, I have all kind of chargers but I need to know the polarity of the original charger.
I am familiar with the other requirements like volts and amps.

Some information I have available:
Acer Aspire 4720z : positive at center, negative in the outside. Acer Aspire One : positive at center, negative in the outside.
Like most electronics, it's positive tip, negative barrel/ring.
