    Backlit keyboard malfunction.


    Hi,


    I'm using a lenovo legion 5pi laptop with RGB backlit keyboard . The normal shortcut key for enabling backlit is Fn + spacebar . it was fine few months ago but then , sometimes when i change colors using the keyboard shortcut , the backlit turns on for a second then turns of automatically . when the cycle of 3 colour options complete it should turn off when i press the shortcut 4th time , but instead it gives a random colour profile . Everything works fine when controlled through software. but when using keyboard shortcut , this happens .


    I've checked for driver updates , did a BIOS update . but this problem persists.


    thank you in advance.

    :)

    Thanks to all who have participated.

    zbook,

    Step one of your instructions resolved the backlite issue. One driver update was found, and BIOS was updated from v1.3.2 to v1.3.3. Upon reboot the keyboard functions as expected.

    Thanks again.

    regards,

    caffeine,

    On my Dell Inspiron 7779, the backlit keyboard setup is controlled by
    Code:
    and I think your first check should be to run that utility so you can see what it has been told to do.

    You mentioned messing about with function keys. The F10 key toggles the keyboard backlight so if you find yours is set to off it is probably as a result of the F10 key rather than some fault. This would match the symptoms you have described as well.

    Whilst your version may not look exactly the same as mine, Dell have been using QuickSet for keyboard control for decades so it is bound to be the utility controlling yours as well. If your version does not appear to behave itself, I suggest using your Dell Service tag to go to your Dell Drivers & downloads section so you can get another copy of QuickSet for you to install.
    - While you are there, check for an updated Bios as well.
