i just got a x50v the other day. got a sync cable for it thats supost to charge it as well..... its not charging at all. nothing. i leave it off and the amber light is on, but once i take it off to power on, it wont. i have to take out the batery and put it back in to get it to power on. then it tells me that its shutting off due to low power... it was charging for 5 hours. its realy frusterating right now. it has a new battery in it. i even tried hard reboot, but it didnt even have enough juice to finish that up all the way. i even pressed the little button on the back and nothing is working.
