Triton 500 (PT515-51) looses AC adapter in games

I own this laptop for 1,5 years and face a really strange issue sometimes. In certain games (Far Cry 5, The Outer Worlds for eg) while I'm playing laptop loses the AC adapter. Like it was unplugged, but it wasn't. Simply replugging it into the laptop doesn't help, need to reconnect it to the wall supply. Looks like the AC adapter, for some reason, goes into some kind of protection mode, I dunno. I didn't notice any correlation or logic in it cause more demanding games like Battlefield 5 never did such a thing. Can't say it bothers me a lot cause it happens extremely rare, in certain games, and "restarting" fixes the issue and it won't return in my play session.
