When powering down the (A)TC-780A the CPU fan stays running, or worse, ramps up to 100% and stays running. I want to reiterate, this is with the unit off. The power light on the front is dark. Clean install of Win10, all drivers and BIOS updated. Any help appreciated.
Hi Gary, this issue’s having a lot of potentially fixing methods. Older power management driver Install an older Driver for Intel Management Engine InterfaceFirtst try V10 then V9 (if V10 didnt work) Hardware collision Something may block shut down - Especially HDD, if there is with cooperate with SSD. (only if your system is located on the SSD) - Reformat the HDD or use the different partition. BIOS bug Re-Flash your BIOSWipe CMOS - Unplug your MB from the power supply, remove the CMOS battery and then plug the battery back Motherboard fault Your motherboard may be defective, in this case, if it’s still under the warranty, send your MB back to the supplier and want a new one. If it’s not under the warranty, it’s time to start thinking about a new.
