MacBook :: Screen Dims While Watching Full Screen Video?.OS X :: Screen Changes Brightness Level Automatically / Flickering On Screen.MacBook :: Screen Dims And Brightens Randomly.Hard drive access doesn't seem to coincide with the dimming. Has anyone noticed a very slight flicker on their new MBPs? I have a new 13' and, every so often, the screen brightness dims and then brightens very quickly (happens in less than a second).The option for auto-adjusting the screen brightness is off so it's not that particular function.It's most noticeable on all-white backgrounds both on AC and battery power.
