My refurbished laptop is about 1 month old. It is Lenovo ThinkPad T480s. Recently, the laptop base at the top side will get hot easily. I need to shut down and wait maybe 20 minutes for it to cool down.

May I know how can I solve the overheat problem? I am afraid it will burn the motherboard.

Thank you.

Need to replace the thermal paste. Check the fan and heat exhaust got dust or not

Thermal paste hardened. Need to replace it.

Also, clean the CPU fan too. Thin laptops usually have very thin fan but lousy at thermals and will fail overtime.

look like the shop doesnt do good job in refurbished ur laptop..overheat usually because of the CPU fan got a lot of dust blocking the air circulation and old thermal paste which is crusty. need to do deep cleaning and change the thermalpaste to a better one. hope this help you

I tried to open all the screws at the base of the laptop and unable to take it out, although can turn the screws. Then, I opened the cover to take a look. All the screws have a thin layer thing blocked me unscrew. In this case I cannot clean the fan and apply thermal paste.

The problem is I cannot take out the screws. There is a tiny layer locked the screw. I can turn the screws using the screwdriver but cannot took it out.
