    Brightness switches not working in HP laptop after installing windows 7 Professional

    I have an HP laptop which came with Windows 7 Home Basic but I removed that windows and installed a new Windows 7 Professional (32-bit).Everything is going well and the windows never reported about any error.I noticed this issue later but now unable to fix it.Actually after installing windows 7 Professional, I am not able to use the brightness keys.When I press these keys,brightness icon appears on the screen but doesnít effect the brightness.It is draining my battery at a rapid speed so please suggest me a way to fix this.

    Hi,

    A switch from Win 7 HB to Win 7 Pro is not an issue and this upgradation really helps.

    Your problem must have come from the version change but either a incomplete installation or from a faulty driver file that controles display matters for you.

    Try to download a fresh copy of Display driver file from Microsoft website and install that in your system.
    Or go for a re installation with complete features installation.

    Thank You.

    Hello,

    This is not a hardware problem your laptop is extremely fine.
    All you need to do is just reinstall your laptop mother board drivers.
    Then automatically your bright keys will work.
    Hope it will work for you.
    All the best

    Hello friend..............


    i will help you solve this problem just follow the below steps.

    When the external AC power supply is unplugged from a Laptop, the LCD display will
    dim to conserve on battery power. During times of heavy battery power operation; such
    as during the startup or boot process, the display may be very dim or barely readable.

    If the display remains dim when the laptop is operating on the Windows desktop, follow the steps below to resolve problems with display brightness.

    Restart the laptop with AC power.

    Follow the steps below to determine if the dim display is due to ahardware failure:

    1.Connect the AC adapter to the notebook and a working electrical outlet.

    2.Power down the PC by pressing and holding the power button for 5 seconds.

    3.Press the power button again to start the computer.

    If the display is still dim after restarting with the AC adapter connected, try changing the LCD brightness.

    All the best..............
