The bios can only be lifted up to 3.17, if the machine got an original Lenovo battery for 150 bucks. So i can only point that this bug did not occur under 14.04 LTS. The system was reverted to Ubuntu Mate 15.04 now and show the same behaviour, screen brightness turns to highest or lowest at boot. Last state was not saved like in earlier ubuntu versions.

Now bootup again, the login screen and your desktop is on lowest backlight power that can be set, maybe you have to lower the light to see your display. You have to power the backlight up with the Fn-Keys after login., but this will not survive next shutdown.
