I seem to have a problem when charging my 4700 on the ac adaptor..not long into the process the device will 'lock up/freeze' while charging on ac power on the docking cradle. I try to soft reset but without success. Only a hard reset will resolve the issue but I will be required to pair the device to my laptop again in order to sync. this has happened several times. HP have replaced both the cradle and AC adaptor but the problem persists. There appears to be no problem when I charge using the USB option alone. Any thoughts ???? Gregj
