So he hooked up a spare Keyboard and Mouse, turned it on, and it booted and stayed on for 10 minutes then died.
They WERE Macintosh ADP keyboard and mouse, right? Other things might fit in various ports, but they won't work, and could probably cause damage.
I put it all back together, turned the power switch on in the back...
...nothing, hit a bunch of keys on the keyboard (because it is artistic not to label the power button as a power button)...
...nothing.
Yeah, the power switch on the back must be on, and then you soft-power up the machine from the keyboard. On the Mac ADP keyboard, the power button has a triangle on it. Hold it for a second or so.
Most Macs also have a power button (marked with an (I) symbol) on the front of the machine somewhere, as well. My old junky 7200 has one on the front-left of the case, somewhat hidden under an overhang. Again hold the button in for a second or so.
So I wonder, if the Rayovoc battery on the mother board is dead, would it cause it to act like this?
It will cause the Mac not to boot properly, but IIRC, it'll do the "Dead Mac Bong", rather than being completely unresponsive.
