Hello!
I also have that problem but this is on my cpu problem. because it always throttles and i can't fully use my 2.3 ghz full clock on my cpu.
my laptop is n4050 but i have i3 and amd 7450M (which is written on the hardware properties of CCC)
i brought it back and the technician says there's no damage to the system. BUT I ALWAYS GET THROTTLED OUT AND IT SUCKS CAUSE I CAN'T PLAY SMOOTH GAMES.
Well I used my own method (which is on top) but i can't fully play some games requiring a 2.3ghz minimum system requirements.
Games:
Dead Space 3
CS:GO
Torchlight II
I did use Dell PC diagnostics and still throttle exists.
This is Shaun again.
