    • A possible crash on the PowerBook G3 when removing an attached USB keyboard at the same time as putting the unit to sleep.
    • Hot swapping a media bay device into a bronze keyboard PowerBook G3 would not always recognize the device.
    • Using the Target Disk Mode feature on the bronze keyboard PowerBook G3, a user can only use the SCSI ID setting of 2.
