    Popeye's solution works, device manager, find display adapter, and properties, drivers, update drivers, locate drivers... Choose the 2nd on the list, usually the previously working one, select next, OK, it works! Now brightness slider bar on windows 8.1 issue is fixed!

    choosing microsoft basic display doesn't solve the problem..

    i changed high performance gpu to power saving gpu now its alright but when i switch back to highperformance gpu screen goes blank..hv to remove the battery and boot again..so i am staying with intel power saving gpu

    Probably won't be optimum graphics especially playing games but hopefully you will eventually see an update available in Windows Update that actually works.

    You can also search around the internet to see if somebody has found a good driver.

    Did you try going back to the first one to see if it was just a glitch that fixed itself by switching between them?

    Has Lenovo posted a new driver?
    I switched back to the Intel driver and it's still locked, but it's locked at the brightest setting, so it's not a big deal. And no, Lenovo didn't post an updated driver yet. Thanks again!
    Same problem, followed the same procedure (except mine was 3000 and not 4000 graphics version ... not sure what that means), and it worked. Thanks! No problem with adjusting screen brightness either.

    Issue not resolve


    Good Day, I followed Popeye's steps but I was unable to resolve the issue. I tried the second driver down as well as the Microsoft standard with no luck. I am unable to adjust the brightness.


    I am going to try a clean boot to see if there is something on that end stopping me from controlling the brightness.

    Note that I can slide the brightness bar up and down but nothing happens....
