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.

    Yes!

    Thank you very much for this, it has worked perfectly!

    I've been unable to change the brightness of the laptop, it was so bright it was hurting my eyes, I had to install a 3rd party dimming program just so I could use the laptop, I'd called ASUS who insisted that there was nothing wrong with it of course.

    Last night when I unplugged the power, the screen dimmed and went really dark, this morning when I came to use the machine it was still really dark, now I had the opposite problem it was too dark to use properly!

    I've just done what you said and installed this older driver and it's perfect, the brightness can be changed, previously it only changed it a tiny amount rather than the full range :)

    Very happy as I got this laptop to work on when I'm away from home and this has made it much better, thank you!

    I had the same problem on my Lenovo Ideapad.  Your solution worked, though I had different drivers to choose from--two versions of Intel HD Graphics 4000.  I selected the 2012 version instead of 2013.  It worked!  Thanks.
