I have my gumstix board working with 3 AAA batteries now. The Wiki
page about battery power mentions that 3 AAA batteries will last about
a few hours. On the gumstix board running on batteries is there a way
to tell the current power level of the batteries? I just want to
figure out if gumstix/linux provides a way such that it is possible to
figure out ahead of time when the batteries are low on power and need
to be replaced.
