the dim, blank, and sleep timers can all be set separately for the
externally powered case, and set to 0 to disable them completely. by
default they're set the same for both battery and external power. the
one setting that's different in the default config is that on battery,
they system will eventually shut down on its own. on external power,
it will not.
(btw -- that last setting (when to shut down when sleeping) is set to
just 1 hour. since the 1.5 can stay asleep for several days before the
battery goes, one hour is probably a bit aggressive.
