Question New Asus ROG Strix charging issue

[Xrib]

I have a month and a half old Asus ROG Strix GL503-GE
i5 8th gen/ 8gb ram/1 TB HDD/256 GB ssd/1050ti
I've been using it to play games with a cooling pad and as the processor was getting kinda hot (upto 80-90 degrees) I reduced the power level to processor to 75% in the battery management section
Recently while in the middle of playing a game the fps dropped to a third and I realised the laptop was "plugged in" but "not charging"
I restarted which fixes the issue but starting the game causes the issue to start again
Game was far cry 5
I've also ran GTA V and NFS payback with no issues

New to using gaming laptops, any advice much appreciated

I also have the same issue for the same laptop except its i7 .idk whats going on and i think i have made a big mistake.I ran watchdogs 2 , gta V and final fanatsy xv at 60 fps or above and now it only runs at 20 fps or below.My old pc with Fx 4300 and gtx 1050 gives me an fps above 45 on all these games and now i dont know what to do .

I need a permanent solution.

Lots has happened since then but when I faced it again somehow the pc was running it on intel hd graphics not the dedicated gpu, just right click on the program and change it on "run with graphic processor" option
