    Hello everyone,

    I have a 2010 Acer Aspire 5742ZG (p614g32mnkk) with original BIOS v1.01 running on Windows10 for 2 years now (original was Windows7 Home) and I have recently done the following hardware upgrades:

    from (original specs)...

    • HDD 320GB
    • 4GB DDR3 1066Mhz
    • Intel P6100 (2.00GHz - no turbo)
    to (all specs are brand new)...

    • 2.5" SSD 240GB
    • 8GB DDR3 1066Mhz
    • i5 540M (2.53GHz - 3.07Mhz)
    The problem is that after doing all of these upgrades and reinstalling windows, I can no longer change the brightness on my screen like I always did... The workarround I found for this was to install and activate the BASIC WINDOWS GPU and then change the brightness to the level I want... How to fix this?

    So did the original have drivers in Win7 or older that also makes a difference as well. Anything with drivers older then Vista isn't going to work as it did before. Did you install the drivers after doing Windows update to make sure all correct update and drivers where installed?

    No...

    I have had Windows 10 for 2 years, but recently I did that hardware upgrade I got mentioned above.

    After doing that hardware upgrade, the windows brightness no longer works.

    What can I do to fix this? The only workarround was to install and activate the BASIC WINDOWS GPU and then change the brightness to the level I want.

    You don't mention how you used to change the brightness. Did you use the keyboard or the Action center before?

    Using the keyboard for this have never worked for me when running W10, even though my model was sold with it later.

    Also, have you tried other drivers than the one that gets automatically installed? (besides the basic one)

    So what site did you use to load the OEM driver? Sometimes custome system comes with custom software and if you don't install those it will not work to control that hardware feature.

    You need to install the display drivers for your Intel IGPU.

    You can either get it from Intel.com or from your laptop's manufacturers site.

    Before the hardware upgrade which was also running Windows 10, I used the internal keyboard of the notebook to the change brightness only (because I always use an external keyboard since I got used it both at home and work).

    Sadly after the hardware upgrade, the notebook keyboard stopped working for unknown reasons...


    Sorry but... what is an OEM driver?

    I have owned this notebook for almost 10 years, and I have formatted arround 20 times using the following method (which always worked 100% including brightness... only after the hardware upgrade that I successfuly did, it decided to stop working...):

    1. Get Win10 Media Creation Tool into my 8GB USB;
    2. Do a fresh Windows 10 install after wiping out all the data within the drive (through delete partition action included within the Win10 Creation Tool);
    3. Once the PC is fully clean and a fully fresh Win10 is installed, I then proceed to allow Windows updates to update everything.
    The brightness always worked after this through my keyboard keys, but this time after the Hardware upgrade (new SSD + new CPU + new RAM) my keyboard stopped working and as consequence, so did the brightness through any forms...

    Althought, I noticed that the Windows updater now shows a new "Intel Processor" update that I previously never had. Maybe this is the reason of conflict?


    I used the intel feature to automaticly detect whatever updates I needed and it turns out I don't have any available updates...

    I'm really desperate at this point... the only workarround is to activate my Basic Microsoft GPU, decrease the brightness, and then activate the dedicated ATI GPU again... which is ridiculous and awful since I always have the need to constantly adjust my brightness... any ideas? =(

    Yes... sadly I have exhausted that possibility aswell.

    I installed the Catalyst Software Suite and it was still a dead end...

    I was always able to change the brightness just after a 100% fresh windows 10 install... so it cannot be drivers... the CPU hardware must have messed that... but even if it did, how can I fix that???

    Someone help =/

    Are you sure that wasn't before Windows Update installed drivers from internet? I think it sounds just like what happened.
