No, the SS4 power supply is a dumb smart supply - it has a "soft" switch,
but no memory as to what state it was in before, it always powers up "off".
When I was getting a new SS a few years ago, the choices were a SS4 or SS5.
I didn't care (I was never going to get a 24 bit frame buffer for a SS5...)
but told the people buying it that if it was a SS4 it had to have a UPS
so it would stay running. Since a SS4 + UPS was cheaper than a SS5, that's
what I got... Since then it has happily sailed through the odd power
glitch that has been experienced (and I now suspect that the SS4+UPS was
a better option that the SS5 would have been anyway...).
Without a UPS so you can avoid the power outages, you're out of luck
(a SS4 doesn't draw a lot of current if you leave the monitor on mains
power - so a tiny UPS is sufficient - mine is about the smallest
available, and will keep the SS4 running about a half hour).
