I haven't had it to the point of needing to take the battery out (in fact, haven't touched the battery yet). Sometimes, it'll just go blank/turned off and I need to reboot. But so far, rebooting has worked. I'm having the issue of the lcd coming on after being locked - even with no one near it. Ghosts ;-)

Sarah, are you getting a new AC cord from enTourage? With the pin size being small, I'm hoping they will just send out new cords to those who have had problems - even if they aren't in the US. After all, I think the international shipping of the unit is a regulatory issue (like some software can't be sold outside US), but the cord should be exempt.
