Hey,

Sorry if this has already been posted but i cant find it anywhere using the search.

How do you turn the RP on and off, does it just run as soon as it finds power or is there a some sort of button/switch to turn it off/on?

Thanks

Paul

No RasPi power switch: plug in to turn on, unplug to turn off.

thanks very much for the answer. sounds very fair, saves money with not having to add power switches and still easy to manage.

The option of course is to wire in your own switch.
If you are more worried about ,spelling, punctuation or grammar you have probably already missed the point so please just move on.

yeah, adding a switch to the power cable itself would be very easy and also cheap for people who dont mind cutting wires as you can pick up on off switches (rocker or push switches) from ebay for a few quid, inside a usb cable, the 5v wire is red, so just cut in half (or wherever you want to add your switch), and wire in a switch upto the 5v cable, some switches also have a prong for ground, for these ones just add the black wire (ground) from both sides from the usb wires.

If you really want a switch it should be on the 230V wire to cut stand-by loss in the transformer too.

I think there is some possibility to add an on/off switch that does a nice and slow kill of all software running on the Pi.

But that involves two GPIO pins, the abuse of some electronics and a script that is run on an early runlevel...
