I have recently upgraded from Windows 8.1 to Windows 10 and it appears that it mostly successful. By and large I'm pretty happy with the upgrade however there is now a problem with turning off my laptop.
When I use any of the 'off' variations (shutdown/hibernate ext.) the laptop acts like its turning off and boils down to a low hum - but never actually turns off. Moreover the button becomes unresponsive to any further presses so that I can not turn on my computer without first enforcing a 'hard' shutdown by holding the button - which is bad for my laptop and will reduce its life considerably.
How can I resolve this?
Here's some info in case it's needed
