Brightness not controllable or adjustable Yoga Model 20175 Laptop Windows 8.1

I started using a brand new AC adapter directly from Lenovo after my old one stopped working. At first everything was normal. After restarting my computer a few hours later, the brightness is set and cannot be adjusted with the keyboard, slider or within settings. The autobrigtness is not turned on nor is power saver. It was dim and at night after being in sleep it was bright but at neither time could I change or control the brightness. Today upon restarting it is still in a dimmer mode and I cannot make the brightness increase. I did not update anything else software or hardware and everything else is original to the laptop (no replacement parts).

I have checked to make sure Adaptive Brightness is turned off in Display Settings and also made sure the Auto-Brightness is turned off. The brightness is at 100% on the slider and settings but the screen remains dimmed.

Thank you!
