    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?

    If it's an extremely high pitched noise, then it's inherent to core 2 duos, and there is nothing you can do about it. Mine does that, but it's pretty tolerable.

    not only Intel C2D are affected even some AMD laptops. But it's "normal", at least you can't do anything against it.

    Ok. Thanks for the clarification. Wonder why Core Duo 1 (Yonah) never had this problem?

    I believe there are some settings you can use in RMClock to get around the circumstances that cause the buzzing. Supposedly it has something to do with how the processor steps up and down to save power.

    funny you should mention buzzing noises, my t2010's fan is starting to give off a pretty annoying buzzing sound even at the lowest fan levels.

    If it's anything like my P1610, it's the inverter for the backlight for the LCD display. It buzzes when it's not running at full power. So that's the reason why you are only hearing it on battery power, as your power saving features dim the backlight by default to save power. When you are on battery pwer, try cranking the LCD brightness all the way up (usually Fn key + ^Brightness).

    You'll sacrifice battery life, but it will be silent.
