Uso del computer (cont.)

Smaltimento della batteria e della pila

Il computer utilizza una batteria agli ioni di litio e una pila di riserva. Per informazioni sulla sostituzione della batteria agli ioni di litio del computer, vedere “Informazioni sull’uso della batteria” nella Guida dell’utente di Dell. La pila ha una durata estremamente lunga ed è possibile che non ne sia mai richiesta la sostituzione. Tuttavia, qualora fosse necessario sostituirla, l’operazione deve essere eseguita da un addetto autorizzato al supporto tecnico. Non gettare le batterie e le pile insieme ai rifiuti domestici. Per informazioni sul più vicino centro di raccolta di pile e batterie esaurite, contattare i responsabili del servizio smaltimento rifiuti di zona.
