You know how on an iMac (or iBook for that matter), before it turns the screen off altogether, it darkens the screen to conserve energy?
Well often on my iMac it will auto-darken to about 70% brightness, and when I move the mouse it will auto-brighten again to 100%, but them moments later auto-darken again back to 70%. If I leave it idle again it will auto-darken to 50%, then auto-brighten back to 70%...and so on.
Once it does that, I cannot get it to go bright again unless I put the Mac to sleep, then wake it up, or restart. If i go to the brighten controls (F14-F15) it claims to be at full brightness, but that's clearly not the case.
What's the deal?!
Can I just turn the auto-darken thing off? coz it's not a big deal on a desktop PC anyway. I couldn't find anything in Energy Saver.
Thanx in advance
