Hey all. My 12" PowerBook (G4 1.33 GHz 512 MB RAM) recently had a problem with the DC-in board, which I replaced myself. (I'm no longer under warranty.) Everything with the DC-in board replacement went smoothly, but after sealing the case up, I noticed a couple problems. One was that I had forgotten to connect the internal speakers back to the logic board, and the other was that my AirPort extreme suddenly stopped finding wireless networks, although I could still turn it on and off from the menu bar.
I let it be for a couple weeks, but eventually I decided to go back in to reconnect the speakers and see if I couldn't locate the problem with the AirPort. The speaker issue was of course easily solved, but I couldn't find anything out of the ordinary with the AirPort. It could be the AirPort card itself - I don't know; I haven't tested one that I know to work, but that's going to be my next course of action.
But then a new problem developed. After closing the case up the second time, I noticed that the computer was no longer recognizing my superdrive. It just doesn't even show up in the disk utility, and the system profiler says "no burning device was found" under disc burning.
Before you think that I made the same mistake as with the speakers - I didn't. I looked inside again, checked the connections, and it still doesn't recognize the optical drive. I know the drive is getting power, however, because it whirs and spins away on startup. I also took the whole superdrive out, opened it up, and replaced the disc inside with the OSX 10.4 install disc, and tried booting the computer from that disc holding down "c".
Anyways, I found discussion of this type of issue once in this forum before, and I tried all the solutioins offered there - PRAM/NVRAM reset, PMU reset, and open firmware reset. I just don't know what could have happened. And although the DC-in board issue was my first time opening up my powerbook, I'm by no means new to the inside of computers. I was very careful to replace everything exactly, to be gentle with all the parts, and to be properly grounded.
So - does anyone have any thoughts on the optical drive or the AirPort? Any ideas would be much appreciated.
Thanks
