Just got my X and made a big mistake right out of the box - 'pulled' the yellow pull tab in the battery compartment and kept pulling until the that entire piece peeled off (thought it needed to be removed so that the battery would make contact). So, then put the battery in and .... of course ... it will not power on. The only 'how to remove battery' info I'm finding says 'it's easy - just pull the yellow tab'! Does anyone know how to remove the battery when the yellow tab is no longer there (other than just prying with a screwdriver or such)? Yikes, has anyone else done this? thanks.
