heatsink cleaning after effect

[notre]

hello, just now i went to service center to clean and replace thermal heatsink and everything is fine included overheating is no more, but when i try to play game(the same game before this) my laptop is suddenly auto-shutdown with no reason and no heat problem, it's happened to me every single minute in-game. what happen? anyone help?

please dont reply me "perhaps your laptop is overheating". no, my laptop is not overheating after service. i can feel the air from laptop fan and it's not so hot. before this, i still can play any game for a long session even my laptop is overheating.

It is possible that your system was damaged while it was being serviced, or that something was not re-installed properly. This symptom is typical for a heat and/or power issue. I would return to where you had serviced to make sure all was reassembled properly.
