    voltage, amps/watts, the connector, and the polarity of the connector must match.

    i know the voltage, amps/ watts are values written on the adapter.

    what do u mean by "connector",is it the jack that goes in the laptop?

    And what's the polarity? is it a value written on the adapter too?

    Polarity refers to the negative and positive portions of an electrical circuit. Just like a car battery which has a positive (power) and a negative (ground). I wouldn't worry much about polarity though. As long as it's a barrel connector (which most laptops use), then negative will always be the outer lip of the cylinder and the positive terminal will be in the middle of the barrel. What's important though is the physical diameter of the connector.

    Yes connector is the jack that goes into the laptop.The voltage should be exact.The amps it's ok to be more but not less as the laptop draws only as much as it needs.

    For polarity(In the connector) look at the diagram at this link:
    Polarity symbols - Wikipedia, the free encyclopedia
