There is a small battery on the motherboard which is used to maintain PRAM settings. If it is completely flat it can impact on the ability to restart. I'm not familiar enough with the Mac Pro to be able to give you reliable advice, but if history is anything to go by the battery will be a 3.5V half-AA Lithium type, and should be fairly easy to locate in a Mac Pro. I used to buy these from Dick Smith, but I haven't had to do so for many years so I don't know if they still carry them. Batteries Plus might be another source.
