Fn+Left arrow key combination also not working for volume down while Fn+Right arrow for volume up is working.

I tried installing a third-party brightness control software while in Safe Mode but then realized it won't work until I log in to my account, in normal mode, which I cannot do since the brightness is at zero. Safe Mode doesn't allow adjustment of brightness since it cannot load the display driver. Hence, I'm not able to increase the brightness anymore.įYI, the "Up" arrow button works normally but the combination "Fn+Up" doesn't work while "Fn+Down" does. To check if Fn+Down was working, I pressed them and the brightness went down to "0" and now the screen is always black both while plugged-in and unplugged.
