My Macbook started turning itself off automatically on Thursday. No warning, no nothing, just an odd "click" sound and then all power goes off. Bleah. Gave it one day and hoped for the best, but by Saturday I had to take it into the service centre. Some logic board fault, most likely, they said. And wouldn't you know it, they're out of logic boards for about 2 weeks. Man, two months and it goes cuckoobananas on me. Oh well, while my Mac's recuperating, I downloaded ObjectDock as part of turning my PC into a Mac. Mmm.
