HI, Thanks for the comments and info.
I'm not really fussed about overkill. What I particularly want to know is, if I turn the screen curtain on, will this undermine any benefit of having the screen brightness at 0? I understand screen curtain does not turn the screen off, but is it therefore the same as having it on with low brightness? I kinda got mixed messages from you both but what I think you're both saying is that screen curtain makes no difference so I can have it on and brightness set to 0 and this will conserve some battery life. Is that right? Thanks again for your help. Nic -- You received this message because you are subscribed to the Google Groups "MacVisionaries" group.
