I've got a powerbook, and I'm having the issue of my computer not realizing it has bluetooth (built in). I've read a bunch of other threads of people with this issue, so it seems like a fairly common problem. Summary of the problem: I got my computer about two years ago, and bluetooth worked for about a day. I haven't had any bluetooth devices until now, so I've never worried about fixing it too much. I don't have a bluetooth icon in my menu bar, the system preference pane doesn't show up, and the system profiler says I don't have a bluetooth device (under bluetooth or usb). Fixes I've tried: I've had the computer for a couple years, so restarting is obviously not going to magically fix it. Bluetooth firmware update - won't run because it says I don't have bluetooth hardware. I deleted the bluetooth plist files from both my home directory and from root's. I reset the pram. I did a reset-all from the open firmware. I reset the pmu. I've unplugged everything, taken the battery out for 10 min, and then started it back up. I haven't reinstalled the OS because I don't have my install disc any more. Can anyone think of anything else to try, or am I just SOL? Thanks!
