iMac display sleep "during I work"?
Hi everybody,
I have a little bit strange problem and did not get a solution yet.
My iMac is basically going to "Display Sleep" modus during I am working on the computer! This happen just random but like every couple of minutes. Sometimes I can work 30 minutes without a problem and sometimes it happen every 3-4 minutes.
Does not matter which application I use, skype, safari etc. just in the middle suddenly the screen goes off, I move the mouse, screen comes back and I enter my login infos again.
I already checked on energy safe modes etc. all is on NEVER (besides that this should not happen anyway when I work on my Mac). I also downloaded the Coffeeine App and disabled sleep complete without success.
I would be happy if somebody has an idea how can I trace this problem.
thank you in advance,
Oliver
iMac, OS X Mountain Lion (10.8.1)
