This discussion reminds me of how picking up my water bottle from the cup
holder in the center console of my Honda CRV will often cause the "radio" to
switch from playing CDs to FM radio. I have experimented some and it is NOT
my accidentally hitting the FM button with the water bottle, it's proximity.

Your keyboard may have a flaky solder joint so that connection is more
susceptible to EMI noise.

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
grounding does not seem to help.  Might running the USB cable from the
keyboard to the computer through a toroid help?  (I would need a big toroid
to pass the big USB plug.)

You could try unplugging the keyboard to see if that stops the
behavior . Maybe it is acting as antenna.

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

[Denis Heidtmann]

I assume this is due to static electricity creating some sort of
disturbance.

I have an AST usb keyboard.  Keyboard presses are what normally wakes the
computer.  Moving or clicking the mouse does not.

Although this is but a minor annoyance, I would like to figure out what
part of my system is responding to what I assume are electromagnetic waves.

Ideas?

I vote ESD/EMI.  Can you try maintaining contact with a grounded object 
while rising from the chair?  Say the outer shield of a USB cable that 
is plugged into your computer, for example?


Back when I was using a crappy plastic chair mat, merely leaning back in 
my office chair would sometimes trigger my oscilloscope.  Even with a 
hardwood floor you could be experiencing an ESD event, particularly with 
the low humidity we have right now.

Re: [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.

I think you will see in my earlier message that I cannot use the mouse to
come out of suspend.  I can drop the thing from a few inches off the
desk--no  response.

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

It's the anxiety sensor. I first learned of these from John, a 
technician at Prime Computer back in the late '70s. Every summer we
