Regain Bluetooth functionality by replacing your Bluetooth board.

  1. Lay the iMac display-side down on a flat surface.
    • Lay the iMac display-side down on a flat surface.

    • Loosen the three Phillips screws securing the rear panel to the iMac.

    • These screws are captive in the iMac. The center screw will stop turning after about 3.5 turns and the outer screws will stop turning after about 5.5 turns. Do not try to remove these screws from your iMac.

    My iMac has only ONE catch, the central one, so the two outer screws are not to be touched.

    In fact, I tried so hard to unscrew them, with a good screwdriver, that my hand hurt. Knowing that some times captive things (like these screws or a faucet) can be already at the end of their travel and we only lock them further into that position, I tried both screwing and unscrewing to no avail.

    Looks like one of these screws is not like the others... a security Philips?! Never seen one of those before.

    Please Note: If your iMac has an antenna for the airport extreme and not the bluetooth card. Don't buy the bluetooth get the airport extreme instead. Also, some newer devices may not work with these units.

    • Bend a paper clip into a hook and use it to pull the Bluetooth board up off its socket on the logic board.

    • You may use a spudger to remove the Bluetooth board, but be sure to only apply upward force as any sideways force may cause the connector to shear off the Bluetooth board.

WARNING: The last iMac G5 17" ALS (no isight) to be made does NOT have a dedicated bluetooth board.

I followed this guide and ended up removing the fax/data modem which is above the bluetooth board in this guide.

The last iMac G5's (17" no isight) to be made have a Airport Extreme/Bluetooth combo board:

This is located to the right of the battery.
