    Until you find a fix for the lighted keyboard, cover your keyboard with a small towel.
    Another option is to use the power supply's on/off switch after you shutdown your system from the front panel on/off switch.
    You might be able to fix the problem by using a PS/2 to usb adapter.

    Thanks for the reply, well it's pretty annoying to do that everytime i am going to bed. I have tried with usb too (the keyboard is usb but i use ps2 adapter for full nkro)
    Could there be any jumper on my motherboard that can disable it? I think the problem is "ebu" or something like that.

    You need to read your motherboard user manual to see if there are any specific bios settings or jumper settings that deal specifically with usb power settings.

    We can best help you after you create a detailed hardware list in the PC Specs portion of your
    forum profile http://forums.tweaktown.com/profile.php?do=editprofile at the bottom of the
    profile page or in your forum signature http://forums.tweaktown.com/profile....=editsignature.
    Be sure to include brand names and model numbers.

    I believe that my motherboard got something called "5VSB" That means 5 Volt Standby Voltage.
    Here is manual off mine motherboard: ftp://europe.asrock.com/manual/Z77%20Pro4.pdf
    It looks like an jumper but i am not sure.

    The only 5VSB reference in the user manual describes the usb pin layout. There isn't a jumper block for 5VSB on your board.

    Disabling some of the following options might "fix" your keyboard.
    Some of these options need to be enabled if you want to wake up your system from sleep or hibernation.

    from page 62 in your motherboard user manual:
    3.4.8 ACPI Configuration
    Suspend to RAM
    Use this item to select whether to auto-detect or disable the Suspend-to-
    RAM feature. Selecting [Auto] will enable this feature if the OS supports it.
    Check Ready Bit
    Use this item to enable or disable the feature Check Ready Bit.
    ACPI HPET Table
    Use this item to enable or disable ACPI HPET Table. The default value is
    [Enabled]. Please set this option to [Enabled] if you plan to use this
    motherboard to submit Windows® VistaTM certification.
    PS/2 Keyboard Power On
    Use this item to enable or disable PS/2 keyboard to turn on the system
    from the power-soft-off mode.
    PCI Devices Power On
    Use this item to enable or disable PCI devices to turn on the system from
    the power-soft-off mode.
    Ring-In Power On
    Use this item to enable or disable Ring-In signals to turn on the system
    from the power-soft-off mode.
    RTC Alarm Power On
    Use this item to enable or disable RTC (Real Time Clock) to power on the
    system.
    USB Keyboard/Remote Power On
    Use this item to enable or disable USB Keyboard/Remote to turn on the
    system from the power-soft-off mode.
    USB Mouse Power On
    Use this item to enable or disable USB Mouse to turn on the system from
    the power-soft-off mode.

    Let us know if you are successful.
