Toshiba Satellite will not auto. standy/hibernate

I have a Toshiba Satellite notebook less than six months old and running with Windows 8 and latest updates to date.
My Toshiba Satellite will not auto. standy/hibernate, it will only do it by me executing it manually.

All device drivers are up-to-date, according to Toshiba download site, including graphics driver.
All USB devices have been un-plugged.
I have done a re-boot of the notebook, several times, and it made no difference.
I have turned on and off the screen saver settings.
I have changed and changed back the power scheme settings.
I ran the powercfg -requests tool, and it reported no problem.

I noticed when I ran the Toshiba hardware troubleshooter, it said to turn off the screen saver, but it was already turned off. I noticed in searching the net that other Toshiba users say they have noticed this too.

I also noticed that when I choose my photos as a screen-saver they take a long time to run, or sometimes not at all.

Help in solving this problem is appreciated, and is a learning experience for me. Thanks, Hasiel in very cold Alberta Canada

I had the same problem and I am also using a Toshiba Satellite notebook, all I did to fix this was run the "Refresh your PC without affecting your files" and it now works as it should.

Thanks AlphaBay, will give it a try and report back.
