    I have a G4 Quicksilver with Superdrive. I ran the apple hardware test today and it gave me a code of "Error unet/5/15" which i learned means replace I/O logic board. What does this exactly mean???


    Quicksilver G4 running 10.3.6, 867MHZ, 512 ram

    It means the logic board has something wrong with it, and is likely going to fail. So, when the machine stops working, you'll know why.

    that means if you still have applecare warranty time left on the machine, it's time to give them a call. If not, time to start looking for a certified repair center, 'cause you got problems.

    Do you have the unit connected to a network? Simple items first. Bad cable, bad router? If you do, disconnect it and rerun the test. If the same error comes up, sorry to say, it's the MLB.
