Have you ever been awakened by a loud noise no one else heard? (SNP)   The Healthy You: Health and Fitness Polls

I had an unexplained humming noise when I first moved out here about 37 years ago, that took weeks to figure out. What it turned out to be was, a train going down the tracks more than 7 miles away. At a certain speed, infrasound would be conducted through the earth, which then would cause the structure to resonate at a higher odd harmonic, like how a frequency multiplier circuit operates in an older UHF radio transmitter, where the carrier needs to be several times higher frequency than any quartz crystal can possibly oscillate.

So human ears can't hear the fundamental frequency, but each peak would cause nonlinear coupling into the trailer house structure when I had the little trailer. So let's say that the actual sound from the train was 5 hertz. The 5th harmonic would be 25 hz, the 7th would be 35 hz, and the 9th would be 45 hz, which would be audible but a deep humming.

Step outside into the open and you'd hear nothing at all. In the days long before Google it took a lot of detective work to figure out what was happening.

They are going to ask tech anyway.

Maybe a bug can be found, or possibly a fix that doesn't break something else. It can take 3 minutes for the complete edit screen to fully load. Not always but it's due to slow and laggy connections.

It depends on the computer, too.

I have one notebook that, while kind of slow, didn't lag and it may have just died this afternoon when water splashed on the keyboard. That was the favorite one to do forums and stuff because being portable, I could carry it to wherever I was doing things.

There are a couple of others, but they have issues of their own. I need to crank up the 12 year old Dell notebook which happens to be a 64 bit and would let me install Ubuntu 18.04-LTS, but it's kind of slow to boot and seems to have some other issues, since modern on-line stuff requires what would have been a top of the line multi-core maxed out gaming machine a few years ago.

Thus bloatware in operating systems and on-line stuff all produce enormous demands on systems so it can take 20 minutes to just write a letter using a million times the computational horsepower we used to land on the moon.

The GUI interface, multiple fonts, and of course with Windows, all the "phone home" and sifting through everything you do so it is a good little spy for the Thought Police, all of that eats up a LOT of RAM, a lot of processor cycles, ties up entire cores, and burns through your available internet bandwidth pretty fast. Throw in the Russian botnet load that malware adds to your system to help your smart light bulbs and refrigerators run Twitter bots, Facebook bots, online illegal sales, keep backup copies of ch*|d p0*n and such, and it's a wonder the internet still works at all.

And of course there's always those full video ads that obnoxiously are served up from news sites, or the ones that figure out your machine never fetched their malware riddled ads at all, and instead of the content it serves up a "I see you're running an ad blocker".

Like "Yes, of COURSE I'm running an ad blocker - for the same reason a space capsule has a heat shield on it, to protect the occupants from the intense heat of re-entering the atmosphere. Because your obnoxious ads bring my network to its knees. And if you refuse to serve up the content, I can feed the couple of lines from the preview link into some search engines and probably find the whole article that someone else managed to bootleg, because until your outfit learns some basic network etiquette, all you are doing is driving a lot of traffic away from your site. And furthermore, I intentionally will boycott any product that is spamvertized by some obnoxious ad that keeps me from getting to the meat of the article. Quit doubling down, maybe just put little one-liner text things that don't kill my bandwidth, and I'll be nice and let some ads pass. But when these ads show up like an attacking army in force, their attack will be met with all the resistance as if it were an invading army, with whatever can be brought to bear to stop them.

"And I'm mild mannered compared to some. Maybe that latest DDOS attack was some disgruntled person who just wanted to see a simple news article, you flooded him with crap, so he didn't get mad - he took another swig of his Mountain Dew, crunched another Dorito or two, wiped them on his 3 month old dirty shirt, and with a few crumbs falling out of his beard, he called in a favor from someone in Russia that helped him mine a couple of bitcoins last month so he could stay in his parents' basement, pay the electric bill, and order himself a nice new waifu body pillow."

At least that's the internal dialog I kind of think of when I see those obnoxious ads - lol.

How much water splashed? Can you dry it out?  Your area is very hot right now.

I was rinsing out a tub with a hose about 10 feet away. It was probably as much as 1/4 cup that hit the actual keyboard.

Once I realized what had happened, I removed power, removed the battery, and ultimately had the entire motherboard out to try and remove all traces of corrosion and such.

I got it totally dry, clean as could be determined, put it back together, and it refuses to boot. There is power consumption happening but further troubleshooting will require a LOT of time and energy to find what the moisture killed.

.

Not that particular model. It's been discontinued for a while. But I want to find one that is a lot faster to boot and to run, that can handle more memory, has maybe at least 6 to 8 cores at around 4 to 5 ghz. It needs to have a longer battery life, and much more responsive video playback.
