hi, I recently clean installed windows 10 and I now have a problem that the brightness sometimes works in reverse...eg when i plug the charger in the brightness will go to 100% as it should but the screen will go dark as if its on 0% brightness..what i have to do is lower the brightness to 0% in order to get 100% brightness..just doesnt make sense...i have tried any solutions i have found on this forum but none have worked...i have updated windows, scanned for hardware changes, updated the graphics driver in device manager and uninstalled it and reinstalled...nothing has worked and its getting very frustrating...can anyone help...thanks for any replies
