A known issue with MacBook Pro's is that the WiFi reception is poor when running in clamshell mode.    A workaround for this issue when using an external monitor only has been to close the MacBook, wake it with a USB device and monitor attached, and then re-open the lid.


Unfortunately, this doesn't work in OS X Lion.   That's because as soon as you open the lid, Lion re-detects all the displays and re-enables the LCD monitor.  I'm sure in some circumstance, that's very helpful.   But not in mine.


Does anybody know of a way to keep Lion from re-enabling the monitor whenever the lid is opened?



MacBook Pro, Mac OS X (10.7)
