Ive been having a problem recently where when im gaming my laptop will just shutdown like 20 minutes in. It isnt a problem with temperature, it never reaches above 75 degrees c. , I sent it in to asus for them to fix and they replaced the motherboard and sent it back and the dame day i get it back it shuts off, ive noticed that when im gaming when my laptop is plugged in (when charging, not at 100 percent batter) my screen brightness keeps flickering, when its fully charged (plugged in) it hasnt shut off yet, for a week, does this mean there is a problem with my ac power adapter thats making it shut off?
