My W8.1 was misbehaving, it wouldn't sleep automatically. I normally use http://www.karenware.com/powertools/ptstopper.asp a great little piece of software to force it to sleep or reboot etc. I end up with these on my desktop. Neat shortcuts.
I replace the default icons with these http://www.iconarchive.com/show/red-orb-alphabet-icons-by-iconarchive.html
Then I read http://www.fixedbyvonnie.com/2013/11/windows-8-1-wont-sleep/ and picked up some tips. Disabling IPV6 and stopping Sky Drive from syncing amongst others seemed to do the trick. Now it sleeps automatically and wakes by mouse.(usb)
At present I have this.
Thanks. I'll give it a go.
I have changed the power options in the control panel as per "http://www.fixedbyvonnie.com/2013/11/windows-8-1-wont-sleep/#.UuWdcrTn-Os"
A first step as it were. Will try and see how it works. Its happy hour now and " She who must be obeyed will be demanding some wine"
Cheers and thanks
