I have a HP ProBook 440 G1 laptop, and the cooling fan isnt working. It boots into windows and everything, but the fan doesn't spin. It only spins for a split second and then cuts off (as if it got power only for a split second). I have disassembled the laptop carefully (it still works) and I want to know what the issue is. Is there a way for me to test the fan outside of the system? What is the reason the fan is behaving like this? Any and all help is appreciated, Thanks! ☺️
