If your battery is Li-ion than it will not hurt it to stay on charge. Not sure about other batteries though -Jeremiah
________________________________ Hello, What is the best way to operate a laptop when on the AC adapter, with the battery in place or removed? Am concerned with battery life and number of cycles. Battery is always down a little after a shut-down and restart on the power source, does this constitute a "cycle"?
