    Hi, at what time I install Windows 7 in Compaq CQ40-641, I am unable to regulate brightness of LCD Screen, unable to control the brightness in keyboard, as well as how I will adjust the brightness. ? I am familiar with that by going on the way to the control panel / open Power option and go to bottom of screen, and adjust screen brightness control. That’s cool by means of control panel however it’s not working by means of keyboard. Thank you any suggestion regarding to this trouble.

    1.Download sp45713.exe (I couldnt get WMI to work, so this was the only one witch worked)
    2. Extract files
    3. Burn ROM.iso to DVD or CD (bootable usb sticks didnt work for some reason)
    4. Restart computer whit CD or DVD inside
    5. Update bios, and enjoy the show.
    NOTE2: After update my computer didnt turned on first 3 times. Dont panic.
    6. Brightness works perfectly now. (If it dosent, you probably forgot to install Quick Launch Buttons, HP 3D Drive quard and ATI video driver and control panel)
