RPI Power off

#1 Post by Deltasierra » Sat Mar 27, 2021 7:25 pm

Hi to all,
I'm completing my C172 homebuilt cockpit drived by an RPI and just prior to finish cable routing I've a doubt... :?:
In many web page articles I've read that is dangerous for internal RPI SD card, interrupt power by pulling or pushing the plug for shutdown!
My RPI power cable has a switch that I using for powering on/off. Now my question is: is this a correct way to handle RPI shutdown or is it necessary to use GPIO pins with a proper Python code to deal with a switch ?
Thanks.

You can either turn it off from Air Manager or use this:

Yes Ralph, I know this option, my question is oriented to know if the switch that is present on the power cable that now I'm using for powering on/off could be dangerous for RPI SD card.

It’s been discussed on the forums a few times. Search is your friend.

That's my point :) It's not the proper way to shut down the Pi. It'll probably be alright for most of the time, but you'll always have the risk of corrupting the SD card.

Ok, I'll follow your suggestion Ralph, and will try to add a dedicated hardware switch for shutting down RPI from Air Manager.
Thanks.
