Hi,
That is aweful battery power.
If you don't want the screen on a Macbook use the dimming option, "FN"
+ "F1" to dim and "Fn" + "F2" to brighten.
Also, you may want Coconut Bettery, a free utility that sees what is
wrong with your battery, or merely tests it for what you should be
getting.
Thanks for listening,
Alex,

Hmm that seems way too low actually, I get around 5 hours on my 2.4ghz
macbook with wireless off and that's without touching the display
brightness or doing any other tweaks. If I turn that down I can get a
little more out of it, and turning bluetooth off will give me another
hour and a half or so, and reducing the processor speed a bit will
further increase it.
Depending on what screen curtain is actually doing to blank the
display it could be reducing your battery life rather than increasing
it. If it say forces the screen to be constantly black, rather than
just turning it off, this would drain the battery faster due to the
fact that the video card is still drawing pictures but Voiceover
ishaving to black them out before they reach the display. In effect
this doubles the number of operations the graphics card must perform.
I don't know exactly how screen curtain accomplishes its task--maybe
it doesn't do this--but it's something to test. Don't turn on the
curtain and see if your battery life is affected. I do suspect,
however, that it works like this due to the fact that it works on all
monitor combinations and there are instances, such as the Mac Mini or
MacPro, where the system doesn't have control over the monitor's
power.
