ESD is tricky stuff, not only does it vary seasonally (the classic example of walking across a rug in the winter and then touching a grounded device) but also it varies geographically (Albuquerque, New Mexico is so dry that special precautions must be taken in manufacturing facilities). Regarding a simple home ground, I must say that I'm a little uneasy discharging unwanted high voltages into the moidst of a (presumably) well grounded laptop computer.
Why not plug the banana plug into the grounded third prong (after confirming that the outlet is properly grounded) of an outlet?
@mhrackin: I recall some recent postings on "Tales from the Cube" (on a sister site) that identified this as root cause of a number of strange occurrences.
Hmmm -- the main tower in my office keeps on locking up for no apparent reason -- we've scanned it for malware and viruses --- we've run burn-in software to stress the machine and wee've also run deep memory tests overnight -- nothing shows up. I wonder...
So what else did you check? How about your "home away from home" office? I don't know how recent the building is, but even in very new commercial space, I've found poor grounding practices that can result in significant ground differences between separate branch circuits even in the same room!

What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
