MacBook Pro Whine Fix

Fairly strange

Just for info :
I have a MBP 2.16 Ghz with the serial starting with W8618 XXX I'ts brand new I bought it last week.
The whining noise appeared when I upgraded to 10.4.7 yesterday. Just after reboot the whine started, which did not occur with 10.4.6.
Anyway the mirror widget does the trick... but all this is very strange to me. It did not whine, now it does because of the upgrade... An upgrade should be fixing things, I guess, and don't mess them...

10.4.7 includes the keyboard update that fixes the USB bug. The USB bug was stopping the processor from entering low power modes. The whine occurs during the low power modes.

Seriously guys, listen to zign, download the mirror widget off the apple website, open it, close it, close the lid of the MBP let it go to sleep, wake it up, and the whine/hissing noise is GONE!!!!! and i mean GONE and now, your system doesnt heat up, and there are no extra apps running in the background

I guess there is no other solution right now.
As a side effect, could it be harmful (for the hardware I mean) to let the MBP in suspend mode (close the laptop at night) instead of shuting it down ?

Sleep/suspend mode is designed so that you can leave a machine off, without having to completely shut it down...so no, it's not bad for it.

As for "solutions," MagicNoiseKiller works the same way the mirror widget does, exploiting the USB bug....it just has a lot fewer steps to make it work.
