the overheat problem is known to me and i would like to state some basic rules to avoid overheating in a typical laptop/notebook:
1. be sure to never block ventilation openings while your notebook is powered on:
a. do not put your notebook on sofa/bed or on a soft surface, if this is the case then put your notebook to stand on a hard planar surface.
b. check the lowest surface of your notebook has an adequate distance between the hard surface where it stands on (check the rubber whick play the role of your notebook's leg).
c. the planar surface where your notebook stands on must be cleaned of granular materials, becouse they could be sucked into the ventilation system and block or lower the ventilation's system eficiency.
2. if your ventilation system is blocked verify it's so by puting a cigarette near the opening where air is sucked up for a short time.
if you are sure the ventilation system is blocked, try to move the ventilation with a slim object until it starts rotating,
if this method fails then your notebook needs to be disassembled until you can see and manually intervene in your notebook's ventilation system.
if you have disassembled your notebook , clean the metallic sheets with a brush and grease your ventilation's motor axis with good quality grease (DO NOT USE OIL OR COOKING OIL AS IT WILL DRY VERY SOON AND BECOME KIND OF ADHESIVE AND BLOCK IT AGAIN)
DISASSEMBLING YOUR NOTEBOOK IS A STEP TO BE TAKEN ONLY IF YOU ARE AN EXPERIENCED TECHNICIAN IN THIS FIELD, I WOULD RECOMMEND YOU TO LET THIS IN HAND OF COMPETENT SERVICES/PERSONS.
