It does: it just leaves the processor halted. So the other peripheral chips are still drawing power. > How much power is saved?

There are fancy Raspberry Pi add-ons that provide a proper logic-controlled shutdown and poweroff, but they typically cost about the same as a Raspberry Pi, or about two year's energy cost for running a Raspberry Pi 4B flat out. cheers, Stewart --- Post to this mailing list [email protected] Unsubscribe from this mailing list https://gtalug.org/mailman/listinfo/talk
