So, if please try adjusting the brightness again. If so> Right-click again on the VGA driver > Then click Enable.Wait a few moments, until the monitor is finished flashing black.Click Display Adapter > Right-click on VGA driver (Intel, NVIDIA, AMD)> Click Disable.First, open the Device Manager as usual.The steps that must be done are like this: Still about the driver problem in Device Manager, which I also learned from overseas technology sites. Reboot the VGA Driver in Device Manager it is also the best method to fix Windows 10 Brightness Not Working in your laptop. Wait for the process for a few moments. If so, restart as usual. Right-click on the VGA driver available there.The method itself is not difficult, really. Now, by returning it to an older version, it is hoped that the existing bugs can be removed, so that the driver can run normally again. Sometimes the updates are still not perfect, so they actually cause certain bugs or errors. What’s the goal? So, not all new drivers run normally. That is, to return the new version of the driver to an older version. Not only updates but the VGA driver installed on the system can also be rolled back, you know. Next, select the Display Adapter option > Right-click on the detected VGA (can be Intel, NVIDIA, AMD)> Then click Update Driver Software.In the Windows search field> Type ” Device Manager “> Then open it.This method I got from overseas sites, and many have successfully implemented it. The goal is to eliminate errors that may exist. Here we will try to refresh the VGA driver using the Basic Display Driver. The function itself is to display the screen, but in a basic function (just so much). In Device Manager, there is one driver called Basic Display Driver. Using the Basic Display Driver from Microsoft It can be the NVIDIA Graphics Control Panel or AMD Radeon Settings. Who knows it works.įor Graphics Options, it can vary depending on the VGA used. This could be an alternative that you might try. But actually, the driver also has a VGA brightness setting. Thanks in advance to everyone would help me and excuse me for my English and for any mistake or omission I made writing the post (I'm a new user).Most people adjust the brightness via the keyboard keys ( FN + anyone from F1 to F12 ) or through the brightness settings in Windows. ![]() If I connect to the computer an external USB keyboard, the arrows of the USB keyboard work properly, but fn + right-arrow is no longer a valid shortcut for increasing brightness level. Is this correct? Could instead be a problem not related to drivers? At this point I guess it could be a driver problem. If I enter the BIOS, also here the two arrows won't work. I also tried to run Xubuntu on a live USB, and also there I found the same two problems. I've already tried to re-install Windows 7 Ultimate with no success. ![]() How to proceed in order to fix these problems. I don't have a deep understanding of the computer architecture, so my question is there is no way to access the brightness control, neither with fn + right-arrow nor by means of the display settings available in the control panel (the slider does not appear in the proper page of the control panel).right- and down-arrow don't work, i.e., when I press one of them nothing happens (but I don't think they are physically broken). ![]() I have an Acer Aspire 5680 PC, with Windows 7 Ultimate.
