i've been experiencing this bug since last year when i got this game, which makes playing not fun. it applies to dawn of war 2, chaos rising, and retribution. the issue is that while playing, the laptop stops charging the battery, forcing me to quit the game, unplug, and replug the charger, not from the port in the laptop, but from the wall.
i don't experience this bug in other games like metal gear solid 5 and fallout 4 in ultra graphic settings
