I've just noticed that my T2010 gives off a buzzing sound. Very faint sound, didn't notice it until today when I was in a quiet environment. Is this normal? I think something is wrong with the AC Adapters (emphasis plural). Previously I posted about the static shock I've been receiving. I think they're due to the 2-pin design of the AC Adapter, lack of grounding to be precise. FYI, I'm using a US AC Adapter in Singapore (240V, UK-plug). Does anyone know how to fix it? Should I get both AC adapters replaced?
