Hi John and Tom, Are you sure that you're using the appropriate keyboard shortcut? On my Macbook Pro, where I have checked the box for "Use all F1, F2, etc. keys as standard function keys" on the "Keyboard" tab of the "Keyboard" menu under "System Preferences", using the Fn+F1 key to lower the display to where it says keyboard brightness is "0 per cent" has the same effect as turning my screen curtain on, according to other users. This also checks out if I try to use the iPhone "Light Detector" app; I get no sound when the iPhone is pointed to my laptop screen when the display brightness reported by VoiceOver is "0 per cent" -- same as with my screen curtain turned on. As soon as I start to raise my screen brightness with Fn+F2 the "Light Detector" app on the iPhone picks it up. Of course, if I don't press the Fn key along with the F1 or F2 key, nothing happens to the brightness adjustment with the above settings.
Are you using external displays like with an iMac? Also, what setting do you use when you check your "Displays" menu under System Preferences? Under the Display tab is the box for "Automatically adjust brightness as ambient light changes" checked or unchecked? When you interact with the slider and push it all the way down to 0 does your screen go dark? Cheers, Esther On Jun 10, 2011, at 15:40, John Sanfilippo wrote: > Wow!
