Hello, I have a dell m6600 laptop which has recently developed a issue with the cpu fan, it was working fine then after turning it on one day and doing some light tasks it shut down and re-booted, I was given a thermal trip error. I checked the fans and found that the cpu fan was not spinning at all, so I ordered one and replaced it and that did not fix the problem. When I run the system test I am given an error for both fans even though the gpu fan is working fine. I have also done a bios update. Any help would be greatly appreciated.
