Last night my laptop (Samsung notebook which is 10 months old) wouldn't shut down. It started to in usual way and screen went black, but blue light stayed on the on button and I could hear the laptop still operating. In the end I closed the lid so it went into sleep mode and removed battery and I could then reboot it and shut it down. Can I ask 3 things? What damage will I have caused the laptop and battery by removing it? Is there a better way to shut down if this happens again? And why did it happen? I remember one program became non-responsive so it might be that. This is the second time, it happened once before about 6 months ago and I had to remove the battery so I'd rather not have to do this a third time. Thanks.
