I recently updated my Windows 8 to an 8.1 and ever since then I can't change my screen's brightness. I have to restart my laptop (ASUS X401U) to make the adjustment appear. How do I fix this?

What you both want to do is open control panel, search for "Update Device Drivers", open that, then under display adapters, double click on AMD Radeon HD 7340M. Go to the driver tab, click update driver, then  my computer for driver software. Then click Let me pick from a list of device drivers on m computer. Click on Graphics version 8.982.7.0 and hit next. The latest version 13 drivers don't work well for some reason on 8.1, but the old version 8 seems to be OK. I hope I was able to help and I hope Microsoft does something about this. If I had known about Windows 8.1 issues in advance, I would never have updated. I can't even open up my bloody metro apps.

I had the same problem, but fixed it. Go to control panel, system and security, power options. Click on your selected power plan "change plan settings".  Then to "change advanced power settings". Scroll down to display, then turn off adaptive brightness. Now restart your PC. Now you should be able to adjust brightness like normal.

    Thank you very much!!!  Everything I tried on my own didn't work.  When I followed your step-by-step instructions the brightness readjusted itself and now I'm happy again. Thank you for taking the time to post this for others like myself who need more in-depth help to fix this problem.

    Hey Daniel, I also used your advice so that I could regain the functionality of the brightness for my Asus. The one thing I noticed though, is that once I reverted to the other driver, certain apps wouldn't work; apps such as Netflix or Skype, and I couldn't play videos with the default windows media player. My theory is that reverting to the older driver restricted function for some flash-based apps?? I was wondering if anyone else was experiencing problems like this...or if you know, Microsoft could provide a fix for their OS...? too much to ask for?

    I have tried this multiple times on my Toshiba laptop but have had no luck. Any other ideas. My function buttons for brightness don't work anymore either. All drivers on my computer are up to date.
