Something very strange just happened to my 18-month-old macbook pro. It was asleep and I went to move it, so I disconnected the usb mouse, speakers, and power connection, and as I lifted the computer off the desk, it immediately turned off. I hit the power button, nothing. I plugged it back in, hit the power button and it started to come on but died less than a second in. I tried a few more times, and got similar results. It would start to power on but just crap out. Not having any other ideas, I disconnected the battery and put it back in, hit the power button, and the computer booted. Can anyone tell me what just happened?
