Cannot adjust screen brightness using function keys anymore! Windows 10

Question

As title suggests the function keys for my laptop have stopped adjusting the brightness for my laptop. I can adjust by going into the settings fine but can't use the keys. I have updated all my display drivers but still no joy.

Answer 1

This seems to be a common issue with current versions of Windows 10. Many users have found relief through the following steps.

On your Key Board press Windows key + X
press M to open Device Manager
expand Display adapters
right click on the current display adapter
click Properties
click on the Driver tab
click on Rollback driver if the option is available

If this does not work please try the following

right click on the current display adapter
click Uninstall
check the box that says, "Delete the driver software for this device.”
exit Device Manager
restart your PC

On your Key Board press Windows key + X
press M to open Device Manager
click on "Action" at the top of the window
click on "Scan for Hardware changes"

Windows should automatically detect your display adapter and guide you through installing the most appropriate driver for your device.

I hope this helps. Please let me know if you need any further assistance.

Hi Alisdair,

Do the other function keys work?

Crazy how it’s only the brightness keys...

Ok, and when did this behavior start? After an update? I’m not super familiar with that model, but I’m researching trying to see if I can dig enough to find the answer.

Also, What version of windows are you running? Click start, and type “winver” and hit enter, a box should pop up. 1709? 1803? Let me know.
