CPU Fan not getting Power ( Fan Works ) HELP
I picked this laptop up to do some maint and sell. The Fan was extremely noisy so like usual I took laptop apart and replaced the fan, when i replaced the fan i replaced the thermal paste with better aftermarket paste. Everything seemed to go smoothly . I booted it up and got the cpu fan error . I verified the fan was working by taking it back apart and hooking it to a small power source. Spins good sounds good. I put back together and it still wont spin . These are all the avenues i have gone
Bios checked fan always on - toggled it on and off both have no change
Removed the battery and all power source- Hoping i could get a reset to maybe something in the firmware
Hooked another fan up ( nothing no spinning )
Hardware is a Fan specific to that build if anyone wants to know.
Ive repaired thousands of laptops and im scratching my head on this one. Flashing the bios help? Updating? Could a sensor be shorted out? What are my options!
