Hi guys,\n\nI have the strangest problem with my Vaio.\n\nWhen the battery is plugged in, nothing works. No power up. Zero. Hit the power button as many times as you want and nothing happens at all. This is with AC in too.\n\nAs soon as I remove the battery, the laptop goes back to normal with no problems at all. Runs as usual.\n\nWould this be the battery or something more serious?\n\nPlease help guys this is driving me insane!\n\nThanks in advance.
