Sorry for the delay in running these tests, but I am happy to report 
that both 6.1 images worked fine on my ThinkPad L380 Yoga (with 16GB 
RAM) [1].  I tried it both with and without the external monitor, as 
well as plugging and unplugging the HDMI cable as quickly as I could.

If you have any more test images, I will be happy to test those also 
(hopefully more quickly)!

  Thanks!
