I have a dell power adapter for my dell laptop (although it's not the original, it was ordered online, it has dell engraved on the charger). Anyway, it stopped charging the laptop, no green light, and it was making quiet beeping noises (from the charger itself). It was plugged into a plug adapter, so I tried it in a different one and now it's charging fine with no beeps.
I know it sounds like problem solved and I'm being a bit paranoid but I want to know whether it's possible that this could be indicative of an underlying fault / cause with the charger itself. Is the charger still ok to use?
