Hello, i have Acer Aspire V3-572G running Windows 10 Home. Sometimes when I shut down the computer from Windows start menu the computer does not shut down completely. The monitor goes blank, HDD stops spinning and the fan slows rotation (but is still rotating) and the power LED is still on. I have to hold the power buttong > 4 seconds to turn off the computer completely. I think the OS sends shut down command to the motherboard but the motherboard doesn't turn off the computer. I think this state is similar to the old computers that does not support ACPI and when you shut down Windows you get message "It's now safe to turn off your computer" - the OS is shut down but the computer is still running.
Why do you think is this happening and how to solve it? Thanks.
