My imac's screen keeps going to sleep randomly... sometime frequently other times with extended intervals...

I have checked forums and re set PRAM and SMC also re set the energy saver preferences, turned off hot corner assigned to screen sleep, installed caffeine (non sleep program) but no luck yet... It still keeps happening... Help!

    Get Temperature Monitor to see if it's heat related...

    Screen Shot 2013-02-15 at 1.35.30 PM.pngCool, thanks.

    What should I be looking for? Temp on start up in relation to Temp everytime it blanks out?

  • BDAqua Level 10 Level 10 (119,040 points)

    Those are all acceptable temps, so not the problem unless one or more gets a lot higher.

     

    Open console in Applications>Utilities, check the system log for the date/time of the last problem  & the Startup right after that for clues.

    A bit of a closer shot..Screen Shot 2013-02-17 at 4.23.35 PM.png

    It's far more helpful to post the text of the log than a screen shot... in console highlight the top line you want, then hold shift while clicking on the bottom line you want, CMD+c to copy, then paste in a reply.

    What does this mean?

    Not sure what that message means.

     

    What is 192.168.1.7 on your network? It seems to have trouble connecting to it!???

    I think that is the wireless connection?

  • BDAqua Level 10 Level 10 (119,040 points)

    But to what? A NAS? A PC?

  • Oonsty Level 1 Level 1 (0 points)

    Your guess is as good as mine... probably better.

     

    NAS.. Network attached storage?... icloud?

    I'd suspect iCloud, but...

     

    DNS+ Proxy+ SMB

     

    Seems like it's trying contact/mount some Windows thing.
