Just bought a replacement AC adapter for my Dell N7110 laptop off the secondary market, and it works fine except that it's emitting a constant high-pitched whining noise. The noise isn't loud, but I have never had an adapter make ANY noise before. Is this safe to use, or should I be sending it back?
It's a genuine Dell product, not an off-brand model, and was kind of hard to find. If I have to replace it, what's a good alternative to the Dell adapters?
