My first re-action would be to remove the battery from the laptop and see if it then powers up. You would then need to test whether the power supply itself is OK. You need someone who has a multimeter to check the output voltage of the power supply.

This is a link to HP in the US where support is available. Also on this link is troubleshooting help. I have translated to Italian.

Il mio primo re-azione sarebbe quella di rimuovere la batteria dal portatile e vedere se poi si accende. Si sarebbe quindi necessario verificare se l'alimentazione in sé è OK. Hai bisogno di qualcuno che ha un multimetro per controllare la tensione di uscita dell'alimentatore.

Questo è un link ad HP negli Stati Uniti dove il supporto è disponibile. Anche su questo link è la risoluzione dei problemi aiuto. Ho tradotto in italiano.
