2 Ways to Fix brightness not working windows 8.1

Brightness problem commonly related with your graphic driver or in some cases Monitor driver. Windows updates and Windows default driver (Installed automatically during Windows installation) most likely to be the culprit.

Before we start:
1. The graphic driver provides by your manufacturer is the most stable driver of all. So if you know how to download it from the support site, try to install them first.

2. If the problem occurs after windows update. You can easily revert back to the older driver by using system restore. Now change the windows update setting so that you can choose which updates you want to install and exclude graphic drivers update from the list.

Solution 1: Remove Drivers by Windows Updates
Windows updates could mess your graphic driver by installing latest driver version. For example version 10.18.10.3368 which remove the brightness functionality. So we need to revert back to previous stable version.

  1. Open device manager (Use Windows+R hotkeys to open Run dialog box, type the command of devmgmt.msc and click OK.)
  2. Look for Display Adapter, expand the list and right click on it and select update driver software. In my case it is Intel HD Graphic.
  3. Select browse my computer for driver software.
  4. Let me pick from a list of driver from my computer.
  5.  Select the previous driver version listed, example: Intel(R) HD Graphics 4000 Version: 9.17.10.2963 
Notes:
In case step 5 does not work, you can repeat the step above and in step 5 choose Microsoft Basic Display Adapter from the list.  In theory - By using basic display adapter, it could reduce the overall graphic performance (However I does not know neither the overall performance change is noticeable nor if there are changes in performance at all).
    Solution 2: Fix Monitor Driver
    In some cases Monitor driver is the problem, windows could select the wrong driver (because it is automatically installed), so we need to fix that.

    1. Open device manager (Use Windows+R hotkeys to open Run dialog box, type the command of devmgmt.msc and click OK.)
    2. Look for Monitors, expand the list and right click on it and select update driver software. (As you see in the picture above it shows Generic PnP Monitor, normally it would show other name such as Generic PnP Monitor (Standard) or a certain Brand name).
    3. Select Browse mu computer for driver software.
    4. Select Let me pick from a list of driver from my computer.
    5.  
    6. Then select Generic PnP Monitor from the list. Click next and restart after the installation finish.
    Let me know if you have any questions.

    How to Fix HP Laptop Brightness Keys not working

    There are several reason that your brightness key does not work. In most common HP model, FN key is important to control certain function by pressing it with another specific key on your keyboard. This includes to change brightness, volume, WIFI, Bluetooth, Screen Lock, and some other functions.

    Note : f your current screen are dim, click on start, type "Change Screen Brightness" on the search box, and press enter. The use the slider to change your screen brightness. The solution below is a workaround to permanently restore you brightness key function.

    1. Install Quick Launch:
    Quick Launch (available for download on HP website) is the software that controls the hotkey function. Try to install this first before proceed. However the brightness failure is not mainly form Quick Launch button but this is a good step to start with.

    2. Check Your Monitor Driver.

    Open device manager and look at your monitor, if it shows standardPNP Monitor, right click on it and select uninstall.

    Then right click again (anywhere you like) and select scan for hardware change.
    Windows should automatically install GenericPNP monitor and now you can change the brightness setting. (Note: Reported by HP G6 Model user).

    IF your Monitor already show GenericPNP. Right click on it and select Enable, if there are no "Enable" option and you only see disable, your monitor is not the problem.


    3. HP 15 Notebook and HP DM4Notebook - Update Graphic Driver:
    One of the solution especially for HP 15 and HP DM4 is to update the graphic drivers. you can obtain the graphic driver from the HP website or from the manufacturer website. For DM4, you need to install the Latest catalayst from AMD website. For HP15 (Intel model) go to Intel website and let it detect the latest driver for your notebook. (for Intel graphic version 8.2 is recommended).

    4. REFRESH NOTEBOOK SETTING
    I don't know what we should call this process, but it is similar to resetting your BIOS.
    (This won't erase your data)
    1. Press Power Button until your notebook shutdown (Force Shutdown).
    2. Remove the battery for 4 minutes and put it back.
    3. Turn on the laptop until you are logged in.
    4. Restart normally using the start - restart. 

    5. Uninstall "IntelliType 8.2" 
    If you installed this software from Intel Website, Uninstall it.

    6. Sometimes there is an odd bug.
    Try to plug and unplug the power chord ( you will see the LED dim) and try to adjust the brightness.

    7. If you have Microsoft Curve Keyboard..
    Plug in Your Microsoft Curve Keyboard, make sure you are connected to the Internet, let it search, download and install the drivers. Try the brightness key after installation finish.

    8. Update your BIOS.
    Go to HP software and download, download the latest BIOS and update your BIOS. This solution tested and work for some HP model such as HP 2000 xxxx series.

    Some notes (will add more update later):

    1. For HP 4540s :  Install HP Hotkey Support File Name : SP56876

    4 Simple Steps to Clean a Laptop Screen

    Cleaning your laptop screen or monitor is not hard since you can you your household products to do it. You don't have to buy a LCD cleaning products since

    1. Turn off your laptop or LCD/LED Monitor :
    Remove any power source such as power chord to avoid the electricity flow.

    2. Create Your own Cleaning Solution.
    You can simply use plain water, but it is better to mix it with organic solution such as vinegar. If you worried about the vinegar smell,  replace it with perfume . (I always use perfume, just make sure use a very small amount, you don't want to work with strong smell, trust me!).

    3. Remove Dust by using Dry Lint and Brush.
    First just wipe your screen without solution, just use Lint, and then use paint brush to remove dust and clean the screens' edge.

    3. Use Lint-Free Cloth or Your old T-shirt
    It does not really matter what type of household item your want to use to wipe the LCD or screen, just make sure it is smooth and do absorb water. Apply a small amount of water or solution we created, make sure it is not too wet. I prefer to use empty spray bottle, the wipe your screen gently. (don't use excessive force to wipe because it could damage your screen pixel).

    4. Final Touch
    Again by using dry Lint Cloth wipe your screen again to remove any excessive solution/water on your screen.

    Summary:
    I'm not a very careful guy, normally I just spray some water and let it there for 1 minute, then wipe with my old towel. I did this for about 7 years for both my laptop and my LED monitor.
