I installed a larger hard drive in my up until then working fine powerbook G4. After doing so, it would not start up, or even give a sign that it had a battery in it. The battery charges, the power cord light changes from orange to green after a while, but pushing the start up button has no effect at all. I put in a replacement used main board that was working in another same model powerbook but it gave the same results, any idea of where to go next?

Thanks,

Jerry
