For some months i have noticed that my notebook has screen brightness problems, when unplugging and plugging the charger, the screen goes black, in which you can only see with a flashlight or in day.
I had a way of dodging this problem by messing with the lockscreen in Windows 10, but in on other OS i didn't have the same luck, i have tried this problem on Linux Mint, Ubuntu and Fedora and the problem still persists.
I've already tried to do a basic formatting of the system and it didn't change, i also have tried installing and uninstalling graphic drivers and it still didn't work.
Specifications of the system:
- MODEL: Thinkpad Edge E420
- OS: Windows 10 Enterprise
- CPU: Intel(R) Core(TM) i3-2310M CPU @ 2.10GHz 2.10 GHz
- GPU: Intel(R) HD Graphics 3000
- RAM: 8GB
