Ok...I tried to install and airport card in my iBook G3. After installing the card and turning on the iBook it wont start AT ALL. I chose "shutdown" from the apple menu before I started the airport install. I remember having problems trying to get my last iBook to start after shutting down. Anyway, I hit the power button, and I hear something going on. The "caps" key on the keyboard lights up, but the screen stays black and nothing else happens. If I press and hold the power button it powers down (or is the spin-down of the harddrive I'm hearing?) I dont know if I can get out of this problem or if I should just save my pennies for a new one. Any help anyone can give me would be greatly appreciated.
