- So anybody who has used a Raspberry Pi knows that it lacks a power button. There are some reasons as to why it doesn't have one, but for many who want to use the Pi for entertainment, like Kodi or Retropie, see it as a big inconvenience. Today we are going to go over the possible reasons the Pi doesn't have a Power Button and also come up with some solutions that don't involve programing, as I know most people don't even want to attempt that.

To those of you who are waiting for my video covering overclocking on the device, the script is mostly done. I just need to cover my opinion of the emulation we will be covering and add some extra bits on the N64. Then I will start recording everything I need for it. I promise it won't take 6 months for this next one.

Notes:
TuyaSmart is the brand name for the solution I currently use. There are multiple versions of the device and I figured I would tell you the one I was using.
I use Amazon as my primary source of online shopping so I only use picture from there. Sometimes Amazon ads can run on here so I wanted to put that out there for transparency sake.
I actually use the USB port on my tv to run power to my pi 4 to power the pi itself, not a AC/DC cable
This is a subject I am fighting with at the moment, I don't want to have to shut it down with a script every time so a button for me is perfect, except for one problem, for some reason I just haven't been able to run the script that installs the button function successfully it always fails, thats with a 3b as well, on my pi4's I have one in a case with a button and couldn't get that to work due to the same issue not being able to get the install script to work and the other pi4 is in a case that takes a small screen, well guess what, the script to run that installs this screen function fails all the time so I am tired and a little sick of it, this has been going on for months and haven't found the solution and the people I have asked have not been able to help.
Next I will tackle groups or forums that have the know it alls that feel it is fun or necessary to belittle newbies and just hope that I find the right person that can help me get passed this drama.
Thank you so much for uploading these Raspberry Pi videos as they have made me interested in emulating games on a device with a OS built specificity for emulation instead of a computer.
I'm glad my content has gotten you try out these kind of OS :)
I just got a pie 3. Everytime I turn it off, I have to re install every thing all over. Why is that? Thank you.
That's just the relay turning on no doubt, not electric snapping. It's just a remote control relay.
The snapping when you press the button is the relay activating
The outro was unexpected XD 10:45
Your videos are professional, well made and just plain fun to watch, keep it up man.
9:11 dude are you a fucking moron, what about a battery hat?
Huh I have a button my my power lead. Go look on eBay they been on sale for years. Where you been??? What’s the big deal
There's a danger usually with data writes if you kill the power by yanking a lead, turning off at the wall etc.
Have you tried any of the retro cases for the pi that look like the nes and such that have a power button on it? They fit the retropie perfectly and most of them have built-in heatsinks
Just look for the + version. The non plus doesn't have safe shut down button.
great video ! is there a difference between using this smart plug and turning off the power switch on the surge protector? that's after i shut it down from ES of course. I've noticed most of the time after I shut it down from the surge protector power switch, when i go to turn it back on the Pi doesnt boot, so i'll need to unplug the Pi power then plug it back in and it will run. Would that same thing happen with the smart switch?
This seems like a smart decision! And also, you can use an app called HomeBridge that you have to code the Pi to make available for Siri or such. The thing is that I don’t know if doing that will affect the Pi; since it would need to be turned on, and you’ll probably run into a problem doing so. I’m still new to do, so idk
Mike jnr the second lol - how sad is that
The more I watch this the Sader it is
I hook my pi into wifi for updates, you can also SSH into it from another device (like my phone) and run the sudo shutdown now command safely.
Unplugging the pi corrupts my sd card every time
Aussie_Railfan SAME BRO
The click when your turn the outlet on is normal
I have a 3B+ connected to an 8 channel relay. I have been getting the lightening bolt. So, I changed to a 3A unit and it is working well...and has the switch like mentioned in the video.
I'm using a 90's era monitor stand with neon-lit rocker switches for six outlets and a master power switch. Simple.
Use rasp controller app
It’s a shame you can’t just press a power button on the Pi to turn it on, and just press it again to turn it off again. I’d like to put a Pi together for my 7 y/o nephew, but the process of pressing start and then scrolling down to the shut down section, and then picking the correct shutdown option, might be too much for him to remember.
the on/off switch on the power adapter is working in reverse (push-in is now off, push-out is now on). anyone has any clues how to revert it back?
Can you emulate the PC98?
After checking Github I found stuff for the PC-88 and PC-FX, but nothing for the 98. Even those other two don't seem to work too well on retropie right now so even if there was one I'm sure it would be a mess.
MikeJRthe2nd Oh, ok
Thanks Mike!
So if you buy a micro USB power supply/wall charger for the Pi3 that comes with an on/off switch It's ok to use as long as you shut the pi3 off from the software first? And I assume you can shut the Pi3 off from a burnt retro game image?
Thnx bro
Until I watched this video I was thinking my SD card was corrupted. My PI4 would still led up Solid RED even after it is turn off and had to manually remove the adapter out of the socket to get the PI off completely. Thanks Man you saved my day. I will go with the extension with the switch so that once I shut down the PI4, I will OFF the extension power to get the RED light go off completely.
The power button should work on nearly any os as it runs in bash and python. So on almost any os it’ll work
U didn't clarify if this button actually shuts down pi3 properly.
I thought I said that for any button connected to the pi itself you will have to code it to have it shut down properly. And any makeshift button using the Pi's power supply will always need to be shut down properly too. If not well... there you go lol
He does at 5:40 and a few times before that
My Canakit came with a micro usb adapter with switch, and I wasnt using it, because I didn't know what it did until I saw this video.
I have the one with the switch built into the power adapter. Works great but have not tried over clocking.
have you ever experienced the switch working in reverse (push-in is off, push-out is on)?

Awesome video, very cool do do the quick 5:01 tip on the solution right away too
My pi set has an power supply with an switch build in
You make a valid case in the earlier part of the video that it is not a good idea to just unplug these units - file corruption, unsaved data, etc... But then you go pretty hard into the idea of using remote/wifi/smart plugs that literally do exactly that - just cut power to the RPi. This is no different than just unplugging it and exposing it to the potential damage that can result from doing that. A switch on the RPi that is monitored by code that can then initiate a software shutdown in combination with an easy way to cut its power is the safest method. So, basically you would push a button on the RPi to have it begin a proper software shutdown - then, once the activity indicator stops flashing (showing that the software shutdown is done), then kill the power to the RPi - whether by a switch in the power line, switched power strip, smart outlet - unplugging it - or whatever. As to how you do this with these emulator software packages I don't know... Haven't used them - but for programming projects - not hard to do.
The thing is, you have to unplug these units no mater what. Even if you shutdown the system properly it will not turn on again until the power is unplugged, then plugged back in. I'm sure I made it clear in the video that you always have to shutdown the system properly before you kill the power with any method, or else it could cause corruption. I didn't suggest a button that would shutdown the pi properly here because I assume for my channel people are watching this for the RetroPie, and a lot of people don't want to deal with figuring out programing. Which is why I recommend these devices.
I think a way to do it would be with an arduino uno and a power relay.
Another way is to buy a case with a power button
Thanks. So glad I ran into this video. I just got the odroid xu4 for gaming and will just get the wifi plug.
I received my raspberry Pi 4 with that chord
I got a cord that plugs into my pi and it has a switch on/off My o.o broke today :(
Those switches just cut the power to the board, they dont shut down the system running on the sd card
@@brentdeacon9218 so I need new pi or new SD card
can i supply power on raspberry pi connecting to the laptop
Your laptop's USB ports don't have enough wattage to power a pi. USB-C ports on your laptop might be enough, but I'm not sure.
Well done on the weight loss dude! Also I’m loving the quality of your content, I’ve subscribed
You go to school so how old are you? you look 30ish
I'll be 25 soon. The facial hair puts like 10 years on me lol.
I believe the Nintendo case has a Power Button that works and it's $20
if you were programming you could make a script that runs rightt before you shutdown and it would save everything
Question: Why no power button?
My guess is no BIOS, and ACPI is a nightmare. Which pushes an 'off' into your booted OS whatever that is. The SOC firmware (whatever this blob is), I think just gets you to the point of booting from an SD Card.
The wireless smart plug does it turn the PI off correctly ?
No, it's no different then unplugging it so still shut it down normally.
MikeJRthe2nd any easy way to do the shutdown? I will have it in a arcade cabinet
Try the ETA Prime video in the description of this video. His involved a physical button that cam be programmed to shut it off properly.
No
Doesn't Junior automatically imply the second?
I actually wasn't sure of this so I looked it up. JR implies you are named after a parent while the 2nd would imply you are named after another person in the family that isn't your parent.
So you shouldn't unplug it as a way of turning it off? Correct?
Unless you shut it down from the Retropie menu first (or any of the other Pi OS), then yes, don't just unplug it to turn the Pi off. The only time that should ever happen is when the Pi crashes and it won't let you turn it off manually first.
MikeJRthe2nd thanks! My dumb ass has been unplugging it 😃🤣😂😃 i keep forgetting its a computer

_ Are we satisified with this ?
_ No.
Raspberry Pi encourages people to build projects that short-circuit their own rules.
Dude I completely forgot about the smart plug! And to get one that's Google assistant enabled and be like "Google turn on my NES" (my pi is currently an NES emulator)
Using sUpPi, all the filesafe power up and down process is taken care of.
Mate, you just have to solder on two pins like in the photo you showed and then use a switch to momentarily bridge them.
a switch or a button?
