It should work if the 20v:
1) end will fit into the charging port on the laptop, and
2) positive and negative contacts are the same as the original.

Polarity.jpg For item 2 above, look for one of these symbols on the chargers. They have to match.

The Voltage has to be the same at 20 Volts, the current needs to be 2.25 Amps or more, so the one you listed will work ok provided the polarity of the connector is correct as mentioned above (most are centre positive but do check first). The connector also has to fit the socket on the laptop of course !

Can anything burn if the Amps are above or under 2.25?

No but if the Amps is lower it won't charge as fast or maybe not at all. If the Amps is higher that doesn't matter, the laptop will only use what it needs.

The ratings you gave for the 'new' charger in post #1 are fine.

Do you already have the 'new' charger ? If not get one with the correct connector by searching for it using the laptop's make and model.

If you already have the 'new' charger you can swap the tips just make sure you connect the right wires to the inner and outer connections, easiest way to do that is to use a voltmeter to check the polarity (+ or -) as mentioned in Liz's post #3.

If you are not confident to do that properly get a new charger with the correct connector.
