I have no idea what is going on here. I got an old MBP v 1,1 off Craig's List. It has a Core Duo CPU, 1 GB RAM, x1600 ATI GPU (128 MB VRAM), and 100 GB HDD. Okay, when this thing is on the desk, it runs perfect. Away from the desk, works until I move while it's running. Or, if I tilt at an angle, it instantly turns off. Is this some sort of cable issue? I have no clue why this would be... however, it's religious. I have tried it many times, and it always fails when tilted at an angle. Anyone have any ideas? I am a little clueless. I want to give it to my wife, but it needs to work everywhere for her.
