Well I brightened up my display with the above command, and then, starting
with a 91% battery, I ran a really intensive computation (bootstrapping the
GCC compiler under OS/2, which uses the disk aggressively). THe battery
lasted 105 minutes. This compares to perhaps 125-130 minutes that I would
get in the same circumstances (91% starting out, heavy computation) with
the display in low position. By the way, I had the display intensity full
on for this whole experiment (lower slider all the way up!)
So it certainly takes up more battery, but it is VERY nice to have this
possibility when it is needed.
Probably the reason that IBM buries this option is that magazines can so
easily beat up on lower battery life, but not quite so easily on a slightly
less bright display. Still it does seem silly that a really important and
useful option like this is not clearly documented!
