A customer bought us this HP laptop that was overheating. The usual cause of overheating is a clogged up heatsink and/or fan – dirt, hair, crumbs etc. block air flow so the fan cannot cool the heatsink which takes heat away from the CPU.
In this case the laptop was getting extremely hot, too hot to hold for long, and the fan was working, loudly at top speed.
As you can see from the pictures below, there was a lot of dust and dirt. We dismantled the laptop, removed the dust (and changed the fan at the customers request), and then the machine worked at normal temperature, fan speed and sound levels.
The left mouse button was also broken…so we fixed that too while the laptop was dismantled.
