Hi BHK6,
the notebook is 1,5 year old and still in warranty. I reviewed the document and also tried everything what is described inside. Something helped a bit, but cooling down the notebook for 5-10 degrees is still a small amount and its still too hot. I will try the hardware diagnostic to see if there will be any error coming out from this. Will come back to this as soon as i will have any result.
Regards,
Tomas
