Will not boot after power off
-
One vital piece of information you have yet to disclose is what kind of power supply you are using. If you're still seeing this behavior with a fresh install, it's most likely to blame here. What we're looking for when we ask about the power supply is what is the specified volts and amps it outputs. If you're able to discern the manufacturer of the power supply, that can sometimes be helpful too.

Sorry a standard MicroUSB charger for a phone its samsung came with my s7. Not sure it is 2.5amp to be honest. will check that. Just tried a new card. same thing
-
Just installed an app on my phone to check the charger, looks like its 1 amp.
will try to find another power supply -
@day2k No phone charges are not going to cut it (most are 2 amps or lower at best) with the RPi3 you need a 2.5amp power supply.

A new power supply and you should be good to go.

New power supply will not fix this issue. It is a bug in the new img. Of retropie. I have same issue using the correct power supply that came with canakit. Only way to ensure the pi will reboot is to pull the plug. -
@grega8233 said in Will not boot after power off:
It is a bug in the new img.
Which new img are you referring to? This particular issue was from about two months ago and seemed to have been somewhat isolated. Were you experiencing it then as well?
Edit: I've had very good luck in ordering Canakits in the past, but as they are not affiliated with the official Raspberry Pi organization, you should never simply assume their accessories are to spec. What model Raspberry Pi are you running and what are the specifics of the power supply? Also, what all do you have plugged into the Pi when you notice this behavior?
-
@grega8233 new image works fine for me and I have a canakit
-
Same issue here using Raspberry pi 3 with the retropie 4.1 release, have you solved it?

@GGHendrix Start a new topic and describe your issue (after reading - https://retropie.org.uk/forum/topic/3/read-this-first)

I am not saying that the issue in this topic is power supply related so it is kinda off topic but I am new to this RPi stuff and I had some troubles too at first, troubles like weird RPi behaviour or emulator performance issues, until I finally got all of them sorted out by getting the "right" power supply setup.
Maybe we can have a sticky link to a wiki page that clearly explains the difference between all those power supply units and micro USB cables.Some people buy the 2.5A USB AC adapter but use a regular micro USB cable from a phone or whatever they have laying around which most of times barely cover 1A or if lucky 2A. Or some cheap sellers sell those PSUs as 2.5A but pair it with a regular micro USB cable which again is not enough to power a RPi3 or maybe even a RPi2. I needed to buy a micro USB cable that clearly stated on the package that the cable is made to use for up to 2.4A.
Then there are the other PSU like the official Raspberry one (white colored) that don't use a separate micro USB cable and therefore should be able to power the device correctly.
I am sure we can reduce the amount of topics by just adding that info somewhere where people can see/read it. Even though there are many that can't or don't read the current sticky link in the forum. But I guess it should be worth a try.
What you say?

We have some information on the wiki, but I'm happy if some more information is added to the existing "read me first" topic - if someone split off the PSU stuff from https://github.com/retropie/retropie-setup/wiki/Overclocking#power-supply to it's own page on the wiki we could link to that (As it's not just linked to overclocking).
Not that I think it will make a difference as you have noticed - people don't bother reading it :-)

I have added some info to the sticky

@mediamogul
I keep having the same issues as this person and it is not the power supply it is due to the load up code, in particular, a failed one. The fail I got was "Failed to start HAProxy Load Balancer. see systemct1 status haproxy.service' for details. " this is where the problem is coming from because on the first load it works fine but as soon as it reloads it fails this part of the code and will not work. -
