A few days ago my laptop has been stuck at the lowest brightness after I turned it on. I tried updating, uninstalling drivers, resetting pc to factory default. Nothing worked for me. I assumed it may have to do with connecting to an external monitor. Since then my brightness has been stuck at the lowest and I can barely see anything on the screen. Also tried shaking the screen rapidly to see if it was a hardware issue, but it seems it isn't.

Assistance would be appreciated.

Thanks.
