Hi, I'm running Windows 10 Home on an ASUS Q551LN 2-in-1 laptop which originally came with Windows 8.1. When I shut down/restart/sleep the machine, it does not shut down - the Hark Disk activity light is still blinking and the normal power button press does not work. If I do nothing, it remains in this state for hours. I need to press the power button for 5 seconds to reset it. Only then I can start the laptop. This happens around half the times. The other half it works normally. I never had this problem with the OEM 8.1 on this machine. Based on other threads - I have the latest Windows 10 updates, and disabling fast boot did not solve the problem. Thanks.
