Hi, i have a Z500 Ideapad,
When i got the brightness problem yesterday, what i did to fix it was
install the latest Intel HD driver and nvidia driver from lenovo's support website
I installed the nvidia first, it didnt fix it, then i installed the intel HD driver, when i was installing it said "do i wish to install because its an older version" I checked the website and it said it was updated on the 16th, so i thought that's strange but i installed it anyway. It then immediatly fixed the brightness problem.
Maybe i was lucky but i hope that this can help some one.
But i have one small problem where the lenovo app's dont work at the moment in the start screen.
