My mum had a Dell laptop whose power supply died after a few years. This was during the era when seemingly every model had a different supply. Dell essentially said "sorry, we don't make those anymore or have any remaining in stock, you're on your own". It was a low-end one (their now-dead 'Vostro' brand), which may explain the service difference, I suppose.
