Dog Whistle Sound From C2D 17" MBP

[lexus]

Not always but alot of the time my MBP makes a high pitched noise similar to a dog whistle. I do not think it is the whine though. Is there anyway to fix this?

Thanks

Ok it only happens when the screen is bright not when it is dim.

Hey,

Is this an early Core Duo version? It sounds like you have the early inverter problem. Just call apple and they'll repair it for you.

No it is a new C2D just out of the box.

Can you tell if it's the fans spinning up?

No I dont think it is the fans.

is it coming out of the left upper corner of the keyboard region? if so, apple can't seem to fix it.

No upper right.

No upper right.

😱 when you browse internet, say with safari, and when you scrolling the page down, does the sound disappear?

when your CPU are run at very high usage, like 100% on both core, does the sound disappear?

if no for both, well, then it's a different problem than the one i had, and you have hope!

No difference with CPU usage and page scrolling does nothing.
