    Have you installed the ATK_Hotkey utility?

    Most likely missing some ATK drivers.

    Please double check

    ATK DRV
    ATK HOTKEY
    P4GX
    ATK ODS2
    ATK ACPI

    some models require all ATK based and related utilities/drivers to be installed.

    Unfortunately, since we will not be receiving Windows 7 based computers until the first week of Oct, we do not have any way to verify in the US if all our drivers are fully compatible.

    Here is the simple trick for you which will fix the problem permanently

    -Open Regedit via run (Windows key + R) "regedit" w/o the quotes.

    Find:
    HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Run
    Modify HControlUser to HControl and the directory should have quotes as you see below, with the assumption that ATK Hotkey is installed in its default directory.
    "C:\Program Files (x86)\ASUS\ATK Hotkey\HControl.exe"
    [Core i3 540 @ 4,170MHz, 1.296v | 12GB DRR3 G.SKILL @ 1442MHz 8,9,8,22 | GTX460 1GB 850/1700/2000 1.025mV | 2x Dell 2007FPb 20" IPS | WD 500GB | HITACHI 500GB]
    IBM ThinkPad T60: [C2D T7200 2.00GHz | 2GB 667MHz | ATI x1300 | 60GB HDD, 1400X1050 | Win 7 Ultimate x64]
