Yup agree on what mudski said. I've gone through more mobos than undies (desktop ones) and never seen a perma-fitted or soldered battery. They're meant to be removable for BIOS reset. Some newer mobos now have a button, to short out and reset the BIOS, but even they have the battery slotted not soldered.

Whats rusty said was spot on, it should sync with the server, but I have seen it be out even when synced.
