Overheating and related shutdown problems are very common in laptops, especially in home use. Common symptoms include some or all from this list;
- Laptop is extremely hot to the touch, especially around the fan area
- Fan seems to be running constantly, and at high speed
- Laptop shuts off by itself when doing nothing
- Laptop shuts off when playing games
- These heating or shutdown problems become worse over time, rather than getting better.

In around 1 in 10 cases, there is a fault with the cooling hardware. By this I mean either a mechanical failure with the fan where it can no longer spin, or spins slowly, or a motherboard electrical fault which exhibits itself by not telling the fan to spin fast enough to cool the laptop.
However 9 out of 10 cases of overheating are caused by an airflow blockage. In these cases, the fan is spinning as fast as it can, but if the hot air is obstructed from reaching the outside world, a heat build-up occurs and the laptop takes the safety precaution of turning itself off, rather than allowing permenant damage to occur.
