as the label said, "Warning, do not remove the battery", is that any risks if I disobey it?
Actually Monika, the guide says that a Tri-wing is needed for two of the screws, which it is. My new battery came with a tool for that but I'd already discovered that it's easy to remove these two screws with a fine straight (non-Philip's head) driver.
Thanks Phillip Takahashi (and your five co-authors). That was a straight forward and clear guide.
Hello
I changed the battery and it keeps telling me that there is replacement needed
Also the indicator said the battery is 150% charged.
Is that normal and how do i remove the status that said the battery isn't ok and change it in to an ok status?
Please help
