Re: Turning off MacBook screens?
Right. The lighting won't be dimmed, it will actually be off. The LCD panel will merrily map its bits and flip its pixels but with no light coming through the display may as well be blank.

So turning the screen down to zero brightness will turn off the backlight yes?

As has been mentioned, the video card is still driving the LCD display with
the backlight off, but the bulk of the energy cost is the backlight, not the
LCD. This is why LCD displays such as clocks or thermometers can run for months
off a little battery. So while you're not going to hit 0% energy use, it's
going to be a lot less than having some backlight on.

James, why is that a shame? Surely you recognize that turning off the
screen would generally not make a lot of sense. These aren't machines designed
exclusively for the blind, so turning off the screen would only benefit those
of us who would not typically use the screen. It just isn't one of those
features Apple or any other computer manufacturer would really consider. You
have the option to turn the screen brightness down to the point where no one
could read it and that alone would help conserve battery life. However, to say
it is a shame seems a little odd when you consider the larger scope here. I am
not sure what purpose this feature would serve even on a lInux machine, but
maybe there is something I'm missing here beyond the possible extension of
battery life.

Screen curtain does not turn the screen off. If you turn the
brightness down as far as it will go, that will help save your battery, but I
do not believe you can turn the screen off entirely-in other words cut power to
it.

Re: Turning off MacBook screens?
Not to mention these options are wonderful if you are a partial with light sensative eyes. Before I got my Macbook Pro, if I had a headache, I couldn't do homework because all my homework was on my gateway, and the bright screen of my gateway would make my headaches worse. When I got my macbook pro, I could work even when I had a headache. I even had instances where I shook off my head pains after a couple hours of writing up estronomy problem sets etc. Justin On Jul 6, 2009, at 10:17 AM, Scott Howell wrote: > Of course don't forget you can turn off the backlight for the > keyboard on the MacBook Pro as well.

Of course don't forget you can turn off the backlight for the keyboard on the MacBook Pro as well. There is an option in System Preferences under Keyboard for this and it is to disable keyboard backlight. Illuminate keyboard in low light conditions and unchecking as far as I know will disable this feature.

Re: Turning off MacBook screens?
Well that may be true and maybe something I'll have to experiment with now that I have a MB Pro. If that is the case, well it would actually make sense on two fronts. First if it does indeed save on the battery, that's great and of course for security. In that regard if you can turn it clear down to 0 and effectively shut it off or substantially reduce power consumption, that would be a good deal.

maybe there is something I'm missing here beyond the possible extension of

Screen curtain does not turn the screen off. If you turn the brightness
down as far as it will go, that will help save your battery, but I do not
believe you can turn the screen off entirely-in other words cut power to it.

Re: Turning off MacBook screens?
No I don't think you are Scott. However, I did read someone that turning down
the screen brightness to zero actually turns off the backlight on the screen -
effectively turning it off. I just wondered if this was possible as I have no
need for a screen bu from waht I remember turning down the screen brightness
increased batery life dramatically.
Thanks
James
