I set my iPAQ 2210 so that it would "Turn off backlight if device is
not used for" 1 min. But it only *dims* it, not turn it off
completely.

If that is correct behaviour, why? I don't need to be able to see
anything until I tap the screen or use a key, when Full brightness
will be restored anyway.

Is there no way to turn it off altogether, so that battery life is
maximised?

I believe that what you are describing is a condition in which the backlight
/is/ turned off, but the screen content is still visible in reflected light.
My impression is that the backlight is the big power hog, so what you are
describing is the desired effect. Perhaps some of the more technical group
members could comment on how much power is used just to keep the screen
"populated" as compared to having the backlight on- my guess is that the
power drain is negligible.

If you desire a completely blank screen (the same condition as when you push
the 'power' button in the upper right corner), you can change settings/power
to turn off the device if it is not used for more than x minutes... but
you'll have to test to see if that interferes with a program you are running
(mp3 player, etc.) or if your active programs (mp3 player, etc) make the
device think it is active, preventing a powerdown.

HTH,

Thanks Keith, that's reassuring.

The application is that I'm using the PPC with a map program
(Memory-Map) and my GPS unit. So most of the time the PPC is in my
pocket, but obviously cannot be switched off because it's keeping
track of my position. That's via Bluetooth, (the only time I've ever
used the facility), which I suppose itself has high consumption ;-(
