Hello, I've recently bought the new unibody MB. Love it, but my I have a problem that I can't seem to solve now. When I put my MB in stand-by mode (screen open) it automatically boots back on after 5-10 seconds. When I close the screen, I can hear (Harddisk is making some noise when it comes out off stand-by) it trying to reboot every 20 seconds. This being bad for battery life and possibly for my HDD too. I hope somebody can help me Thanks.
