Went to L.A. Sunday night and left the box on as usual.
Came back Monday afternoon and the monitor was in power saving mode as it was supposed to be.
Moved the mouse and the monitor came back on and I checked my email.
Noticed an hour later that my monitor was still on so I checked my settings and nothing had changed - 20 minutes selected to power down the monitor.
Re-booted and still no joy. Set the screensaver to come on after 10 minutes and preview was good.
Screensaver doesn't come on either.
This is baffling.
Any ideas?
