I have a Samsung 7 series laptop and recently upgraded from Win 7 to Win 8. I have a Logitech wireless mouse and keyboard.
When I upgraded, both of them worked. When I do a restart in Windows, they both work at startup. If I manually shut it down by pressing the button on my computer, they both work at startup. But when I do a shut down from the power button in Windows and leave it off for some time, they don't work. The cursor pad on my laptop will work, but the Logitech won't work.
I though the problem might be that my Logitech keyboard and mouse aren't supported with Win 8, but I checked with Logitech, and they are.
I also tried shutting off quick start, but that made no difference.
I'm wondering if it might be a USB issue because my speakers don't work either.
Any help would be appreciated.
