My computer is an Alienware 15 R4. The screen randomly starts flickering and dimming. When I connect it to power the flickering decreases a bit and the brightness increases but the screen is still very dim even with brightness at 100%. I’ve had this computer for over two years and still haven’t found the solution. Sometimes it doesn’t happen for weeks and sometimes I can’t get rid of it. [br]
I don’t know if it’s hardware or software problem. This doesn’t happen when connected to an external display. I’ve tried everything I’ve found online
What I’ve tried
deleting screen drivers and reinstalling , reinstalling windows, changing power settings to high performance, changing nvdia control panel settings to high performance, changing refresh rate, etc.
Maybe it’s a hardware problem but i find it strange due to the problem decreasing once I connect it to power. Don’t know what else to try
