The Power Switch Was The Problem The Whole Time - Jody Bruchon Tech

- What do you do if a PC shuts itself off? Look at the stuff that might cause a crash, of course. This time...it was none of those things. The power button was making intermittent unwanted contact.

Since 2005 i have been working with computers and i have seen a lot but i know that there is always a new lesson you can learn, thanks my friend
The best thing to do when troubleshooting is adhering to Occam's Razor, which states "the simplest solution is often the correct one". Start with the simplest thing first and then ramp up the complexity if the simple things don't work. It can be really hard to think that way about problems if you have an advanced understanding of computers because we often think about the worst case scenario.
Also, side note: the power button on my gaming PC broke at one point, and I was too lazy to replace the power button or the case itself, so I had 2 exposed wires that were previously connected to the switch poking out of the case and I would just touch them together whenever I wanted to turn my PC on. I called it "hotwiring my PC". Lol
Yup. I've had the same problem with an old case. Since then I always check, but I haven't seen a bad button again.
Well, you are doing the right thing, this sharing of such a valuable info is a just what newcomers need. Oh Jody, we are so grateful, keep sharing valuable info!
Pulled a full sized desktop machine that didn't look like it had been stripped of useful parts, out of an open dumpster at a friend's apartment a couple of years ago, thinking I would just get parts.. The amount of dust in it was amazing and I cleaned it outside... But then tried to start it up and it wouldn't turn on. But the total lack of response from the power button was suspicious, so I pulled out the connector at the motherboard end and jumped the PWR SWITCH pins with my screwdriver and boom it was on. Everything fully functional. Turns out after removing the front panel that the actual power button that sits behind the front panel had been pushed too hard and had fallen off behind the machine's front panel, which is just plastic that reaches the actual button. The design of the machine allowed the outer plastic "Button" to go quite deep, which is probably what broke one of the plastic clips inside that held the actual button in place.
What was surprising wasn't that this happened, but that the original owners just tossed it in the trash with no attempt to service it, or so I guess based on the dust buildup
The power button is something I would not have thought of. Thanks for the info.
If there's one kind of problem that I hate trying to fix it has to be intermittent faults. This video reminded me of a computer problem that I was really struggling to fix years ago with an Acer Aspire T180 system that was turning itself off at completely random times.
Just like yourself Jody, I checked everything that you normally would that could cause such a fault such as the RAM, power supply, temperatures, etc and everything seemed fine which didn't make sense. I even resorted to doing a clean install of everything and the problem still persisted after that which left me completely baffled as to what was causing it.
Due to the fact that I had no clue as to what was causing the random shutdowns, I eventually came up with the idea of having it setup next to my main PC. That way I would be able to use both computers easily and be able to monitor the faulty computer very closely by trying to use it for everyday tasks, after a few weeks of doing so I finally managed to find out what was causing it to shutdown.
As I was using the Acer T180 to do some web browsing, I found that the Internet connection had suddenly stopped working on it so I checked the main PC and it was still connected. That was the *"Aha!"* moment that I was looking for! I went into the network settings on the Acer to check the network card settings only to find that the network card was no longer present in the device settings. That's when I realised that the network card of all things was the culprit!
This is why I never found those tech support faqs very helpful; they always cover the common causes, and when I get stuck it's usually because of an uncommon cause.
Love this video. Glad you dusted it off!
Here's a weird one you might like:
I knew somebody who had a computer running a dual boot system with both Windows and Linux on it. It also had USB-to-PS/2 adapter connecting to the keyboared and mouse. The set-up always ran fine in Win, but would randomly do weird things in Linux.
The guy was naturally convinced there was a bug in the Linux, but, after thinking for a moment I said "it's not the most likely thing, but keep an open mind: there's a slight chance there could be some marginality in the PS/2 adapter that only Linux is sensitive to".
The guy laughed it off, but then called me back later and said I was right. He had eventually swaped out the PS/2 adapter, just because it was a quick , easy thing to do, and he was out of ideas, and the problem went away entirely after the swap. He cut open the adapter to see if he could find a problem in it, and it had a CRAPPY cold solder joint to ground.
I'd be interested in knowing if you can nail this down in greater detail: Is Linux just faster, and seeing noise that Win is just too slow to see?
It could have something to do with differences in power management between the two. A frequent annoyance is when some mice get put into standby when not moving and Linux registers the waking mouse as if you unplugged it and plugged it back in.
Well there is a first time for everything 😄
being in complete solitary with no interruptions, to think and tinker and make a hypothesis.. it takes ALL of your focus. However, if you don't keep an eye out every day and stay focused with constant interruptions on the current job, you wont see these small thing like your example...
side note: I'm diagnosed 3x with ADD. i never took any prescriptions for it. I'm super focused at happy times of the day but it takes a lot of energy out of me. I've, without experience or skill, stopped jobs for safety or saved a skilled tradesman's ass without me knowing. So, what I'm saying is sometimes, and more than you think, maybe it just required some real focus.
I have fixed one or two bad power buttons with intermittent presses.
Yesterday, I received a new CoolerMaster case to hopefully repair a new build that I haven't been able to fix for three years. It won't boot. A small light on the graphics card lights but nothing else happens. I've replaced EVERYTHING. Everything but the case. I mean, how can the case be the problem? If I wasn't so disheartened by my experience with this machine over the years (Most of the time and for years at a time it just sits in a corner covered by a cloth. There's been too much disappointment.), I'd be looking forward to trying the new case. My thinking now is that the motherboard is shorting somehow or the front panel wiring installed in the case is faulty. I will post my outcome here when I have it.
I’m tempted to send my laptop to you.
Looks like YT hid my comment for some reason. Maybe it didn't like me using the terms "hot" and "wire" in the same word.
I’ve had multiple comments removed without any real explanation.
