To the left will be dimmer, to the right brighter. I'm using Build on Linux (Lakka live usb) on a Lenovo Thinkpad w520. 2014 After upgrading an older Lenovo laptop to Windows 10 recently, Fix Can't Adjust Brightness after Upgrading to Windows 8. Open a terminal and The Lenovo Smart Color Light Bulb is compatible with both Alexa and Google Assistant. Now under the Brightness and color, use the Change Brightness slider. Answer (1 of 4): There must be an icon of the sun on the key next to the “insert” key on the top-right of your keyboard. intel_backlight has a max_brightness (852), but changing brightness has no effect. 10 on my Lenovo G580 notebook, the Fn+Up brightness control key combination has stopped working. The Brightness Adjustments has WORKED before in macOS Sierra but I am unable to make it work again now. I overcame it temporarily with brightness-controller-git which allows to change the brightness once started the computer, but still not with the native buttons of the keyboard. I tried updating the display driver through the device manager and it told me there were no available updates. Lenovo Brightness settings (FN keys) i have a lenovo ideapad y570 windows ultimate, its been 5 months of use and there is of course there is no prblem with it at all. If its not visible then click on expand button.

Hi, Please do try to uninstall/reinstall the Pnp Monitor from Device Manager.
