Well i got my laptop half a year ago and it worked perfectly recently it had problem with the cooling so i send it to warranty and they returned it to but after that i saw 100% CPU usage on the intel i5 7300HQ GPU GTX 1050 2gb 8 Ram. So the CPU when i am playing no matter the game is always 100% and it Lags a lot .Then i contacted the warranty and send it to them after they returned it to me with a note that everything is OK but the same CPU 100% usage GPU 60 to 80 % so what do i do they said that its in purfect condition but after the first send it has this problem
 


no i isnt like the only League clinet is taking 60 to 70% of the CPU by itself i dont know what to do this cpu isnt that bad i saw a reviews on it and it preformed good i dont know what is happeing to his laptop
