sometimes I don't turn it on like for a week so it's not necessary to keep it powerd on. Also every watt counts you know - some smart things, routers, standby device etc, it adds up.
In this case, it's a really simple solution, I'm using too:
Just shutdown from from the LE menu, wait few seconds, till remain only the red led on, than use the switch. If "every watt counts", switch off the power source too. And this can resolve an another question too: "How to start an RPI after full shutdown". ![]()
I'm even using something like this for my PC, I seen once a PC mainboard, burned badly in stand-by, because of a faulty PSU.
