[PLUG] Getting up from chair brings desktop out of suspend

[Denis Heidtmann]

Setting anxiety aside, to address the non-EMI possibilities:

I am running Ubuntu 16.04.  I use the drop-down menu entry "suspend" to
suspend.  The keyboard is about 1 foot from the front edge of a very heavy
wooden desk.  My hands are on the arms of a wheeled chair on a hard-wood
floor.  The return from suspend occurs when I rise from the chair.

I just ran an experiment.  I suspended the computer.  Got up carefully and
went to the kitchen for 10 minutes.   Came back, sat in the chair, then got
up.  It came out of suspend.  I did not even  touch the desk.  I claim
either EMI or gremlins.
