The battery on my my MBPro (3 yrs old) burst out of its titanium casing recently. For months prior to that, a thin vertical line ran down the screen, but machine worked ok. Just prior to battery bursting, the MBPro was behaving VERY strangely, likely due to sick battery? The battery is out of the machine now, but the machine won't start up when plugged in. At the very least I want to get my data off the HD. Wondering if its worth hauling it back to the U.S. (I live in Japan) to take it to an Apple Store for a check. Any suggestions on any of the above?
