I have been following this advice for the past week and it indeed seems to be the case. If I unplug it before suspending AND resume with it being unplugged (in fact, you can actually plug it in *after* suspending, just be sure to unplug it before resuming), the bug DOES NOT get triggered.

However, I should I forget to unplug it before suspending or resume while it is plugged in, the bug occurs and the only way to get rid of it is to press the reset button underneath the laptop.

In my case it is a SAMSUNG Series 5 Ultra NP530U3C-A05EE machine.
