I am using a Razer Blade 15 base 2019 laptop. I removed the laptop battery because my battery was swollen and ran with a direct connection. When I play the game in default settings, it runs but sometimes lags. When I change Nvidea 3d settings to best performance, choose Nvidea rtx2060 in settings, and then when I start a game, my laptop turns off. Why is this happening? I have reset my laptop, but I still have the same issue. Also, change the thermal paste, but the issue remains. But it runs fine with the battery. What is the problem?
