My Inspiron 5559 laptop allows me to play games like on steam or websites while charging without any problems, but any games with higher graphic requirements will make my laptop shut down in 2ish minutes. As soon as I launch Fortnite while charging, my laptop fan will go crazy and I can just place my hand near the air flow and feel how hot it is from 5 inches away. Then after playing for maybe 1-2 minutes in Fortnite my laptop will shut off without warning. The same goes for League. BUT when I unplug my laptop, it will run Fortnite without overheating. and there is lag that I deal with. I made sure there weren't any dust piling inside of the fan or the motherboard. I've noticed that the laptop fps increases while charging and there isn't lag at all. Can anyone help me with my problem so I can play Fortnite or League without stopping to charge up to full battery every 40 minutes? It sucks that I play 40 minutes and wait another 2 hours until the next time I can play. I've tried about everything like updates with windows and AMD graphics software and I am up for about any suggestions.
