Updating bios overheating
It’s nice as a precaution measure, but it might not work if your laptop already has a problem and the heatsink is completely clogged.
I decided to use a shop vac to suck the dust out and it worked.
Common symptoms of laptop overheating include some or all from this list; In around 1 in 10 cases of laptop overheating, there is potentially a phyical fault with the cooling hardware.
By this I mean either a mechanical failure with the fan where it can no longer spin, or it spins too slowly, or a motherboard electrical fault which exhibits itself by not telling the fan to spin fast enough to cool the laptop.
Temperature sensors detect this and will react by making the fan spin faster and faster.
The point of spinning the fan faster is to force more air through the available gaps, and past the hot metal fins to pick up more heat.
As it does so, the air picks up heat from the hot metal fins and takes it away from the laptop.
I will very quickly explain how a laptop cools itself.
