I have a brand new MacBook 2.13. It booted up fine but now will not shut down. I have tried the normal shut down procedure and also holding the power button down for 10 seconds and no luck. If you close the lid it also just reboots. No way to shut it down to do a PMU. Also the computer came with the battery totally discharged. I did charge it to 100%. I can't return it as I bought it from Microcenter in NY and I am in Florida. Anything I can try before calling Apple tomorrow? Thanks
