Only boots with battery
Stop me if you have heard this one before.
I have three mac pro's that run fine, everything seems to work once the machine is up but all three will only power on if and when the battery is installed.
The charger light is green, amber if the battery need charging.
If I try to start with just the mags it just sits there but as soon as I put in the battery it will power on without touching the power button.
If the battery is in first and then I connect the mags it will start normally.

Is this a good question?
