My friend’s laptop recently stopped working as it was overheating. I have run multiple tests on it to no avail. The fan will not spin and the BIOS says 0rpm, I have felt the fan and it doesn’t even try to start. there is nothing blocking it and I have checked the connections and they look good. I have no idea what is wrong with it. I have gotten it to boot once because I was blowing on the heatsink. He got it refurbished and it has worked fine for around 2 years.
