I was using my Macbook 13" laptop tonight when suddenly it froze in Safari and the Force Quit didn't work. Neither did anything else. I held the power button down, and it shut off. Now when I try to turn it on, it starts to boot, chimes, and the little thermometer comes up. It's the one that shows when you have a long startup sequence to go through. Then the whole thing powers off instead of booting. If I hold down the power button until the long tone sounds, the same thing happens. I inserted my OS disk hoping to do a restore, and it just ate that; it won't eject no matter what, and there's no paper clip hole. Power on, progress thermometer moves to about 5% then restarts a couple of times, then it powers off. I powered up and connected my firewire backup HD but it's no help. This Macbook has been flawless since 12/06, and I just installed the latest big OS and Safari updates last night. It worked perfectly all day, however. Any ideas, gang? Don't make me go to the Apple Store on Saturday!
