I cannot figure out what I've done, but under OS X 10.1.1, my 17" Apple flat panel will no longer sleep. The screen saver will come on after 20 minutes, but even though Energy Saver says sleep the display after 10 minutes, nothing. Zip. Nada. Disabling screen saver so it never comes on makes no difference. It *used* to work, so it has to be something I did. But what? Any help would be appreciated.
Best wishes for the holidays.
