Has anyone run into this or heard about this. My G4 Albook 12" works fine in all other aspects. I put the AP card in, and I get the grey apple startup screen, the little segmented wheel starts spinning at the bottom, then stops. end of startup. force shutdown required. I put in another working airport card from another 12" Albook and it did the same thing. I googled and did apple forums but found nothing.
Thanks in advance. I'll try to answer any questions you shoot my way.
