    Hello all,

    I recently bought a Sony Vaio CW2 CI3 which i have been generally pleased with except for one thing: the laptop is emitting some kind of high pitched noise coming from the right side just above the palm rest. It´s pretty noticable in a quiet room and, frankly, very annoying too.

    Have any of you had any experience with this issue on a Vaio CW2?

    I noticed another thread here at the forum ( http://forum.notebookreview.com/sony/470907-sony-cw-i5-high-pitch-sound-2.html) where someone traced the noise to the harddrive and suceeded in eliminating it by replacing the original harddrive with a more quiet model from seagate - anyone else had any sucess with this?

    Easy way to test that is remove the harddrive and boot from cd/dvd/usb with a live linux distribution.
    Noise gone = its the harddrive.

    The HDD is below the palmrest, so it would make sense. And please don't go Seagate for a replacement HDD. Unless it's the Momentus XT. The 7200.4's are notorious around here. I'd say either the Momentus XT, Hitachi 7k500, or an Intel SSD. Any of those are solid choices.

    Solution for high pitched noise:

    1. We have to change the registry.
    Typing in the command line "regedit", you go to the registry key:
    HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ Power \ PowerSettings \ 54533251-82be-4824-96c1-47b60b740d00 \ 5d76a2ca-e8c0-402f-a133-2158492d58ad

    2. Included option in this branch will enable and disable the idle processor. In this case, it should be included.
    To enable one or another hidden parameter, it is necessary to find and edit the value DWORD, changing its value SettingValue from 1 to 0.

    3. Then, through the control panel - power - in the settings mode select power management processor.
    There will be an option disabling idle processor and high pitched noise immediately disappears.
