I had to shut down my system due to a thunderstorm here and no, I have the UPS Backup, but since I was going to be gone and haven't fully got it operational, I shut it down, and now, after 5 restarts it still doesn't see it. I've got to call Apple back and see what the problem is...they had me try to an 'open firmware' test earlier and it didn't work. So, they told me to call back if it kept happening. Thank God I bought a USB mouse and keyboard for my iBook to keep my g'children off the keyboard... One has the same problem, do others? Both of us have models bought in Dec. It could be important if there are others with the same problem...as the fires all seem to be bought in Dec. Wonder if Apple will tell me when I have time to call them. Makes me mad that I can't make it work with Bluetooth after I paid extra to be without lines... So, beware, before you buy Bluetooth mice and keyboards...and let's compare notes about the time we bought them and symptoms. I'd hate to wake up and find my house on fire from my newish G5 iMac. Wonder what Apple would do if that did happen? Pat
