I just picked up an Acer Nitro 5 and set it up tonight. Of course I tried to game on it right away (World of Warcraft) and came across a weird problem. When I was on the game the laptop would stop and start charging, which is quite annoying as it beeps and the screen brightness changes etc. I switched to balanced power management and that slowed down the amount of flickering, but it didn't stop it. I have tired multiple power outlets, with no change. If I do not have the game up or it is minimized the issue does not occur. I am not sure what else to do to attempt to fix this issue. Did I get a bad power adapter?
