You got the junky slim variants then.
I have 2 PS3s, my secondary is a slim and my primary is not. My primary has no switch.
my primary is a fat ps3 and it does have a switch?mate there's a super slim out there google it and make sure you don't actually have a super slim and a slim.
congratulations you just solved your own problem
unplug the ps4 when you're not using it
I shouldn't have to do that though
you could always unplug the ps4
