I was using the Macbook Pro in Target Disk Mode using a external monitor, and when I was done I had to open the case to shut it down. I then pressed the power button to start it up regularly and shut the case again. The computer acted like it went to sleep, so I figured I needed to keep the case open when starting.

As soon as I hit the power button again, the sleep light came on and the optical drive made a little noise, and after one second the light went off and everything shut down again. If I HOLD the power button down then the sleep light stays on for five seconds, flashes rapidly for two seconds, goes off for one second, then back on for a second before finally shutting completely down again. Repeatable.

I do have a Snow Leopard DVD in the drive, but that shouldn't make any difference. I can't eject it either by holding down the eject button while powering up.

I've tried removing battery and power and holding down the power button for a long time. No help.

Any ideas on how to get it alive again?
