Hi all, I got my PB last November. In December I had to get a new battery as it was holding about an hour of battery life. This past week a new problem has sprung up... As soon as I take the PB off the mains it will hold the charge for maximum 10minutes and then hibernates. It normally goes off without a warning although today it told me i was 'running on reserve battery power' .. when the meter displayed it as having 62% remaining. Does anyone have any idea what I can do?
