Laptop fan power problem

[breckjensen]

I'm having an issue with my laptop's fan. I'm on an HP DV7-6100. A while back, I began receiving the 90B error message that says the fan isn't working properly. At first it was intermittent, sometimes I got the error message and sometimes I didn't. Then it became constant, so I disassembled the laptop and made sure all the vents were clear of dust, however I still received the error message. I assumed it was the fan, so I ordered a replacement fan. However, I removed the fan and jury-rigged some AAA batteries together to test the motor on it, and the motor is working fine. As a temporary fix I've got the fan running constantly on an external power supply, but the system it still hitting high heat levels of around 92C when I'm playing a game like Civilization.

Any idea?

Please help.

Thanks!

I didn't find the right solution from the Internet.
