@AlePietro -- one place to look is HP's web-site:

Do a search on your HP's model-number, and you should get a list of all the HP parts for your model.

Of course, if you see "N/A", then the HP warehouse does not have any replacement power-supply.

If that happens, try searching on eBay and Amazon.

Or, support a local owner/operator computer-store business, to see if they have anything that is compatible.
