Recently, Mac 911 has had a big quantity of reports from human beings who’ve abruptly discovered their Mac has lost song of its c084d04ddacadd4b971ae3d98fecfb2a adapter. Traditional is Sarah Clark, whose daughter had intermittent c084d04ddacadd4b971ae3d98fecfb2a losing for a morning, after which the connection failed. The c084d04ddacadd4b971ae3d98fecfb2a menu appeared with an X in its “fan,” and when clicked showed the message “c084d04ddacadd4b971ae3d98fecfb2a: No hardware hooked up.”

As I wrote in December, if you see that message, something worse is afoot than a software configuration trouble. I’ve some greater ideas to strive now, however, introduced to this list:

Reset the non-risky reminiscence (NVRAM).
Reset the Device Management Controller (SMC). This have to most effective restoration power-related troubles, but some humans document fulfillment with this method.
Reinstall OS X; use the directions for “in case you’re reinstalling for different motives.” Whilst a pain and time-consuming, it may repair a corrupted driving force or other problems. Make certain you have got a complete backup first.
if you’re comfortable analyzing hardware and you’ve got a model of Mac that makes it less difficult to get to the c084d04ddacadd4b971ae3d98fecfb2a module (often a combination Bluetooth/c084d04ddacadd4b971ae3d98fecfb2a card), open it up and take a look at connections. On a few models, just like the 2012 MacBook Air, it’s a quite easy operation. IWi-fixIt has illustrated instructions—and sells replacement components. You might additionally be able to lease someone to perform the restore.

Thierry de Montblanc became capable of resolve his “no hardware established” trouble via the remaining step, commencing his 2008-generation Mac laptop and tightening the antenna connection.
