Hey has anyone else expierenced a disappearing of the internal bluetooth module on their aluminum Powerbooks, and on Ibooks with built-in Bluetooth? If you have,if you where able to fix it, how did you do it? Any help with this issue would be greatly appreciated. I've got a 12" Pbook Rev. B (9/03), but I've been reading on Apple's forums that this is a reoccurring problem with everyone. Thanks!
