When the laptop turns on, the fans start than stop working, windows boot's up normally but the fan does not spin. I have flashed the bios with the latest A12 version, I have reset the CMOS, I reinstalled the os, but still no changes. I measured the power coming from the pins when the system starts and it initially gives a ~1.5 volt charge and than 0 volts. While looking around the bios for the 100th time to see if I missed something, the fan started up, I booted windows, but after 2 minutes or so it stopped working again. I also tried changing the power settings in windows, but still nothing. I'd like to add that all this started when I installed speedfan on the laptop, but since than the os has been reinstalled, bios has been updated and reseted so I'm thinking any damage cause by speedfan should have been repaired. Any help would be appreciated.
