System Fan 90b on HP Pavilion G6

The System Fan error is very common in a number of HP Pavilion and Compaq laptops. After the error appears, the laptop automatically turns off. What does it mean? This error indicates problems with the heat dissipation and cooling of the laptop. The laptop may have become too hot and cannot handle the temperature. In this case, you should simply turn off the laptop and wait until it cools down, then turn it on again.

If the problem lies precisely in the incorrect operation of the cooler, then you need to disassemble laptop, clean the cooling system from dust, lubricate it with any machine oil, and also check all the contacts that go from the cooling system to the motherboard. Next, if the cooler rotates normally, without making any squeaks or other extraneous sounds, you need to reassemble the laptop, connect it to the network and try to turn it on again. Everything should be fine now.

If the problem is still not resolved, then it is necessary to replace the thermal paste or the cooler itself as a whole. We hope that this article helped you solve your problem with this error. Stay tuned to learn more useful things from the world of laptops!
