Updated S405 from Windows 8 to Windows 8.1...Can I switch back to Windows 8?

2013-10-20, 20:19 PM

Since I've "upgraded" my screen brightness is much darker and the controls for brightnes no longer control brightness. I HATE IT!! Darker screen drives me crazy. I've tried updating drivers, as I've seen suggested. No dice. I just want to roll back to Windows 8. How can I?

I had the same problem. I even installed Lenovo's drivers for Windows 8.1 and that still didn't fix my brightness problem. I had to install the Windows 8.0 VGA driver in order for my brightness controll to work again.
