Sorry about that, did say it was a bit of a longshot - the reasoning behind it being related to MacBook's graphics memory using the RAM which is being shared with the laptop (as opposed to having dedicated graphics memory).
Do you have any way of making an audio (or even better a video with audio) recording of the high pitched + it stopping while you scroll, then returning again?

Sorry about that, did say it was a bit of a longshot. Not at all, it's worth trying to rule out as many components as possible, thank you. Do you have any way of making an audio (or even better a video with audio) recording of the high pitched + it stopping while you scroll, then returning again? I have just tried to record it on my mobile, but the microphone is nowhere near as sensitive as my ears. I'll dig out a better quality microphone over the weekend so you can hopefully hear it Thanks, Peter.

No luck, even my decent microphone can't pick it up over the fan noise.

If you can post the details about the particular MacBook model you've got (ie year, processor type and speed, etc) then some potential answers may well be available with a bit of furtling around on the web / Apple tech pages - it may well be a known issue with the particular model of MacBook which you have.
It may well be worth your while double checking that you have the latest firmware (if the noise is a known issue, then it might be something which a firmware update from Apple attempted to cure).

The MacBook was purchased in October 2007, immediately after Leopard was released. It has an Intel Core 2 Duo processor running at 2.16GHz. It may well be worth your while double checking that you have the latest firmware (if the noise is a known issue, then it might be something which a firmware update from Apple attempted to cure). Good thought, but it is up-to-date. Thank you as always. Peter.

Could it be the hard drive... have you tried booting from external media?

Was this ever resolved?

I had a quiet high pitch noise coming from my Macbook as well once. i found that it was when the screen brightness was set in the lowest 3 'notches' or the 10, 11, 12th 'notches'. maybe this could be it?

Not sure if this has been resolved but assuming not, high pitched squeals emanating from where you mention on the MX can be sign of a faulty power chip. If Apple agree, they would most likely switch out the whole logic board. Best advice is take it to the Apple Store if you have one nearby.

Hi guys, I have the very same issue on my 2009 summer MacBook (2.13), the last non-unibody poly model. Has anyone come up with a solution to this issue? I have also noticed (as some other people in Mac forums that the sound disappears when I launch some specific applications (e.g. PhotoBooth).
