Mavericks 'close the clam' woes

I typically use my "Retina, 15-inch, Late 2013" MBP at work with the lid closed, connected to an external monitor, a bluetooth trackpad, and a USB keyboard. For the last few months, the results of disconnecting these items and opening the lid have been very frustrating: a black screen that cannot be woken. I end up power-cycling.

I started to compensate by opening the lid before disconnection. For a while, that worked. Most recently, the result of this is that the monitor is alive, but the builtin keyboard and trackpad are ignored. The bluetooth trackpad (if in range) works just fine. This latest behavior seems to me to cast some doubt in the theory that this is a duplicate of MBP Mid 2009 thinks the lid is closed permanently, but only some doubt. Log starts like this, I will shortly post more of it elsewhere.

See a gist containing a whole lot of log, exerpt:

This is almost certainly hardware related. The magnetic reed switch (or hall effect sensor) depending on vintage of the Mac is faulty or failing and potentially voltage fluctuations due to sleeping are affecting it as well.

Any chance you have had it looked at by a tech?
