Which is all directly traceable to various and different types of power connection designs. Also directly traceable to some electronic failures that would never be apparent until a second problem exist or some unique design is used.
It comes right back to basic school science. One generates hypothesizes based upon intimate knowledge of fundamental theories. Then one does experiments to convert that hypothesis into a fact.
Using the 'three prong to two prong' receptacle adaptor is one experiment. A more expensive experiment is the Radio Shack isolator. Moving the entire setup to another building is also an experiment because some buildings (not just the receptacle) could account for that hum.
That concept of hypothesis and experiment is why we teach people in science how to even understand politics. A concept that many forget if not tested by doing - such as by repairing things. We don't repair things to save money or time. First and foremost, we repair things to learn. For some, that means relearning a junior high school science concept - hypothesis and experimentation.
Reading that it is specific to certain laptops says little. If those writers knew, then why did they not also say why? Let me tell you from experience – because most who ‘know’ electrical solutions don’t even know how electricity works AND because Elspode’s problem is often created by something simple but quickly gets complex when trying to find it.
