My HP Pavilion 15 laptop has been having problems with sleep for some time. Whenever it goes to sleep, it won't wake up without a hard power-off and then a full fresh boot. This happens if the system is idle and goes to sleep by itself or if Sleep is chosen from the Power menu. For a while we had worked around the problem by setting the laptop to never sleep, but recently that setting reverted for some reason, so I decided to try to dig into the problem. I tried several things from the web, including confirming that keyboard and touchpad are set to wake the computer from sleep, turning off the ability to power down USB hosts (in case the keyboard or touchpad are connected internally by USB), and others that I can't remember right now. I finally tried a full system reset (after a backup). Now with a fresh install of windows 10, the system also won't power off when I attempt a shutdown - it goes almost off, but the power light never goes off and the screen doesn't go completely black unless I do a hard shutdown by holding the power button down for a few seconds. Some things I found here make me think it may be an issue with Intel Management Engine driver, but according to device manager I have the latest driver and the correct settings for that.
Any ideas what might be the issue?
Thanks
