    Hi, I upgrade yesterday and when I got up this morning I only got what I thought was a dead screen! I thought my screen had died. However, I found my brightness controls are reversed. I can use it knowing this, but am trying to find how to fix it.

    I've got the exact same problem. Any assistance would be greatly appreciated.
    I'm guessing it may be a widespread Windows 10 bug maybe ?????????????

    Hi yes I suggest start up with charger unplugged, if starts ok then prob same as mine, once started up plug in charger, screen will go black, hold function key and use left and right arrows to brighten screen, or can try starting as normal and use function key and arrows as how to fix no idea one person replied with a bios change and running a graphics card app but be honest do not like messing with things i do not know about, bye dave

    I had this issue and I ran an sfc /scannow on the command prompt, I then ran updates and restarted and a recent update seemed to fix it. I have no idea if the sfc /scannow had anything to do with fixing it, but I'd recommend checking for updates and installing any recent ones.

    Great solution. It was really confusing me why the brightness button was working in reverse.. Thanks..

    Mmmm. The problem seems to return after a restart. It's easy enough to either use this temp fix or use the brightness keys in reverse but my customer isn't very happy about doing this on a new computer, which is fair enough. Might have to see if I can get it covered under the Lenovo warranty..

    I have looked on the Lenovo site and it seems they have had this problem before as there is a brightness patch available for this model for Windows 8.1. Unfortunately, it doesn't seem to do anything for Windows 10...

    Well, I have given up and gone back to Windows 8.1. Seems to have fixed the problem..
