Have you guys tried to install Lenovo Energy Management?
If not, can you try installing it and then try to check brightness? Please let know if ti works

i don't think it is a Lenovo based problem. It might be because of win8. I have checked it on a Z580, as you lower brightness from Mobility Center, it lowers the indicator from Energy management too, and aain if you use FN+UP key, it changes the indicator of mobility center too.
