G50-70 can't adjust brightness



After formating and updating my G50-70, the brigtness stopped working. i can't adjust it with hot keys or manually. Tried to update the graphics driver but that didn't work either.  Windows 8.1. Also draining the battery very fast with only usage of chrome.

Please help!

Make sure to load the Lenovo Drivers and Utilities from the support page for your notebook. This should restore some of the missing items and improve battery consumption.

Also - if the notebook shipped with Windows 8.1 and you have not completely wiped the hard drive (fresh install of windows) you can reset the computer to factory load out via the OKR button.
