Hi, taking my notebook to India, would rather not but don't want to pay the postage home. I understand that in many parts of India, the electricity supply can vary. Since a Macbook can run from its own power source (the battery unit), would people agree that it should be fairly safe charging from the mains? I know with desktops, power drains can seriously damage them. Would perhaps a surge protector be a good investment nonetheless? Cheers.
