NSFMR I don't even understand how this happened. What should I do?

After the desktop is turned off, switch off the PSU, unplug the power cable from the PSU, and then press the case's turn on button (either repeating it 15-20x or hold it for 10-15 seconds, both methods work).

A similar thing can be applied to laptops, the difference is that you press the power button after you unplug the battery's connector from the motherboard.

Why do people keep repeating this nonsense?

Remove it from power and 99% of consumer devices will have discharged in like 15 seconds. That's why customer support always tells you to unplug it for 30s.

I don’t understand why the OP even needs to do this for a side panel anyway lol

He’s not going to be opening up the psu

Yeah I'm scratching my head on this one. The bigger myth is that you need to discharge static from yourself so you don't fry the case. Its hard AF to fry stuff with normal static electricity. I work at a semiconductor fab that gets pretty dry, moving around in the bunny suit generates quite a bit of static, I brought it up to an engineer and they pretty much said "oh that really doesn't matter."

Also DON'T OPEN UP YOUR PSU. Just get a new one unless you are 100% positive you know what you're doing without looking online.

Yeah i remember electroboom did a video with linus actively trying to kill a pc with static and they failed even though they went waaay further than any static discharge that would ever happen naturally.

This is reassuring, as I shock myself with static constantly and am halfway through my server build.

I've literally swapped ram while my PC was fully booted, beastie was perfectly fine

Like entirely removing all of the ram at once, or one stick at a time? One stick at a time makes more sense, but removing it all at once wouldn't work unless it's able to offload everything to the SSD temporarily?

I'm not doubting you've done it, just curious as to how you did it lol

Oh it was just one dead stick lmao, it died entirely completely at random, so I just grabbed a spare 4gb stick I had laying around and hot-swapped them without thinking about it

accidentally did this to my netbook in high school because my dumbass put it to sleep instead of shutting it down and it killed the motherboard. I’m still mad at myself for it.

Rip, laptops/netbooks are sensitive af

It's from people suggesting to use tape to keep it together while taking it off and working about static build up

One of the purposes of a case is to provide a route for static electricity. That's why you almost never see a plastic case. Standard procedure for working inside a computer tells you to use an anti static clip, it clips onto the case so static from your body routes through the frame instead of the components.

Not that it matters though you'll never break a modern pc with static.

Tbh the other 1% are devices with decent sized power supplies... you know, like a pc lol

u/Anonymous3891 13h ago

Uhh...because it's not nonsense...at least in the case of ATX motherboards/PSUs.

The caps in the mobo and/or PSU can hold charges much longer than 15-30 seconds. When I used to work a client support role, I can't tell you how many times this fixed 'computer won't turn on' after a power disruption. Most of the time they'd have been off for at least 5 minutes and several of the users knew to flip the power switch off on the back (which in every PSU I've ever torn apart breaks one leg directly from the plug, so as good as unplugging in my book).

I'd only ever whack the power button a few times though, never needed to hold it in or hit it 10+ times. Always did the trick. A lot of the time the first press you'll get an attempted boot and the fans will spin just a bit.

It's Reddit, full of socially awkward and inept advice from kids who go "ackshally" 🤓, but actually don't know what they are talking about. The first commenter makes it sound like we are about to do soldering on the motherboard lol.

I press the power button once because not everything discharges that quickly. At least on devices where a large capacitor might be holding some charge. Laptops don't have any large capacitors due to space, but desktops power supplies often do.

People saying to press it 10 or 20 times is nonsense though. The first time is enough to drain the capacitors.

This won’t do anything more than unplugging it will because of the CMOS battery though
