Why Laptop Turns Off
The problem starts when the cooling module collects too much dust inside. The dust kills normal airflow inside the cooling module. Eventually, the processor overheats and the laptop turns off unexpectedly or freezes.
This problem can be fixed by cleaning the cooling module.
Cleaning The Cooling Module :
Some laptops give you an easy access to the heatsink and fan. In laptops like that you can access the cooling module through the bottom cover.
In my example I had to remove the cooling module. Otherwise, I wouldn’t be able to remove the fan and access the heatsink.
In some models you can remove the fan without separating the heatsink from the CPU.
After I removed the fan, I found a thick layer of dust inside. Cleaning it up will fix the overheating problem.
