John,
Did I miss the log files or ticket you created?
Several of the others in this thread and other similar ones have created tickets and I have analyzed them and no, not all of them have the same root cause.
The lag when lid closed or in replace mode (= only monitors active are through DL) is a Redstone OS bug Microsoft not only accepted but verified fixed in a new OS build!
8.0 M2 won't fix that OS bug. Me working with manufacturers and users to show, with undeniable proof (like logs), that this issue is important will make that bug fixed through servicing before Redstone 2.
But I still don't know which issue you have, just symptoms.
Once I've seen logs collected when the issue was present, I'll be able to say if it's worth trying a new release, not before.
