It looks like Matt's suggestion works. I exited to Windows Then held the power button down till it turned off - A few hours ago. I just turned it back on & it had the same battery life as when I powered down.
I powered down last night with 17 hours of battery life showing (I think I was in Win 7 & not Jfield) & powered up this morning with 12 hours remaining. I'm trying different things to see if I can get the battery to not drain but no luck so far. Really cool machine though!
I am looking into upgrading my GPS equipment. I currently use L1 static equipment that requires long observation times and post process everything. I am thinking of a network rover at this time that I can connect to the Indiana network. The Indiana network overlaps with Michigan and Illinois too...
