For the last 9 months or so, my desk-top PC has been set to go to sleep after 1 hour of no activity (15 mins for the screen). It has done this without a problem until this last week.The screen still goes off, but no sleep for the tower.I have to click the sleep icon myself in the settings.box. What might have happened??
Windows 10 was installed when I bought the tower last Oct.I have not done any updates myself (just what comes through in the middle of the night)----how do I change any settings if that would cure it?
