Windows 10: Laptop switches off when unplugged

Me and my brother's laptops were working perfectly before we updated it. When we updated it an issue came up where we can only use our laptops only when plugged in. If it isn't plugged in, it switches off. Also, even though its plugged in, every 15 seconds during gameplay there is some serious lag. These issues happens to both my laptop and my brother's laptop which are the same models. It happened to my brother's laptop a week before it happened to mine. The battery life of the computer doesn't increase either. Please help.

I am getting BSOD for VIDEO_DXGKRNL_FATAL_ERROR on unplugged startup

I am bit uncomfortable posting the dmp files as they may contain an excess of personal information. Can you advise me on how to analyze them?

I am running the other steps currently. I will post them in a few hours (bit busy tonight).

One notable factor, I specifically started up my laptop right now unplugged. After switching to the Gigabyte's "customized" RTX drivers, I did not get a crash at/near launch. Some of the related threads listed at the bottom the thread page noted that the "customized" driver sets can have these effects.
