Interesting things I checked out and am glad I did!
Lately, for several months, I noticed a fairly loud short hum sound at intervals. Every time I hear it I muse that it must be a power surge. However, I did nothing to check out why it would occur. Today while at the computer I did hear it and checked it out. I followed the suggestions to unplug kitchen appliances (those that I could). I only noticed the sound in that area. I am now prompted to keep alert and follow-up if it continues. One concern was that it could lead to a fire, I live in an apartment building.
Oddly there were a few other things but, like a wisp of smoke have drifted out the window. I guess where I was going was of little importance, getting distracted and trying to pick up a thought after 24 hours is likely not happening.
