Windows 10 brightness laggy – Forums

After upgrading to the Windows 10 anniversary update, FN + Up/Down Arrow doesn\’t work to change my brightness. I have to mash it a couple of times and then it finally comes up about 20 seconds later, Anyone else having similar problems? It worked on vanilla Windows 10, this issue started occurring after the update. Other FN key shortcuts work fine.

update your laptop drivers. Each manufacturer has updates to those several times a year, usually coinciding with their approved video drivers for that laptop. For Lenovo these are called \”hotkeys\” drivers.
