Inspiron 3668 cpu fan keep spinning after shutdown
whether I pressed power button or soft shutdown in Windows, the cpu fan does not stop completely after no video is sent to monitor any more.
if I press power button one more time, pc powers on again.
seems there is 12V leakage power to cpu fan when pc is shut down
similar question asked by other user before. not sure if a solution is found
already tried CMOS CLR jumper
No Events found!

This forum thread may help. The OP stated that the MB was replaced and the problem never returned.

Thank you. I want to add some observation: the chassis fan also does not stop spinning after shut down
when I plug in power cord to the pc that is shut down and powered off, the fans begin spinning immediately without pressing power button. but no POST video.
