    Hey everyone. I recently noticed a high pitched noise coming from what seems like my screen. I have a VGN-FW w/ a T9600, an ATI Mobility Radeon HD 4650 graphics with 1GB dedicated video RAM, the extra-wide HD display, and a blue ray burner. I noticed this noise while I was converting a few movies (wich I noticed was taking up 100% of my CPU) and now it seems to be ever present. The only way to get rid of the high-pitch noise is to either turn the brightness on the screen all the way down or continually move the screen-pushing it up and down and such. Whenever I stop moving the screen, the high pitched noise comes back. I was just wondering if anybody else ran into this same problem. I figure I'll probably give the Sony people a call, but I like to avoid any unnecessary interaction with the vast majority of "customer help" services. Thanks in advance guys!

    Sadly I haven't. I've just learned to deal with it.

    Check out the discussion on the owner's thread for the F series, where some people have resolved the issue by disabling the microphone.

    But no one there has said a word about this phenomenon being related to the screen performance at that thread. However, if memory serves me correctly, the FW owner's thread has had a few posts about these noise issues (but only rarely) over the past year and they, too, were related to adjustments in screen brightness (which suggests power issues).

    Contacting Sony is not a bad idea since the FW series has been around a year and a half and the issue is on Sony's mind because of the F series, too.

    The noise is present in mine too. Probablt the inverter board or something.

    The only difference for me is, it's much more present when the screen is at anything other than either 100% brightness, or off.

    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.
