I have a new Axim (51v) just days old. Yesterday I had it at work, it gave me a warning the batter was low (around 30%), I shut it down and had it in my pocket. When I got home it wouldn't boot, had to do a soft reset to get in and then no problems, batter was around 20%, so I thought probably due to low battery and didn't worry about it. Today, I brought it to work, fully charged. Did some stuff, put it in my pocket for a while. About 45 mins later, I go to turn it on and same thing! Nothing works (the lock is not on by the way). I soft reset it, and it comes on and seems fine, battery is about 81% so that isn't it. Just a little worried since unit is new. What do you guys think? I think I may lock it before I carry it in my pocket to see if that helps, but that is a somewhat pain in the buttocks, will let people know if that helps. Thanks. -D
