I agree with the ESD idea. I set up my 'scope with an unshielded DMM probe
lead spread across the desk in front of the keyboard. I can see very fast
events in the few volt range, but what seems to trigger the wake from
suspend are slower, lower events. No solid correlations, however. And the
You could try unplugging the keyboard to see if that stops the
behavior . Maybe it is acting as antenna.

I vote ESD/EMI. Can you try maintaining contact with a grounded object

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

The mouse is sensing the vibrations you cause when scooting your chair back.
