I recently had to remove the battery to install a ram upgrade in my 12" 1.2 ghz ibook..the manual says upon reinserting the battery, you should lightly press down the battery until the latches lock it into place. My battery does not lock in its set position. I have to hold the thing down as I turn the latch back to the lock position. This is fine with me but if my battery is supposed to click into place I want to know in case my 'book's latches are defective.
