The computer, monitor & a 5 port Ethernet switch are plugged into a
2000VA Uninterruptible Power Supply + Battery Backup. The UPS is plugged
into a heavy duty Tripplite ISOBAR-4 surge protector.
In the event of a power failure that setup gives me approximately 30
minutes to save my work & shut down gracefully. If the power failure
occurs when I am not at the computer, the UPS-Mon software will initiate
that shutdown.
I shut down the computer, turned off the monitor and turned off the UPS
(which remained plugged in to the surge protector).
I turned off the breaker for the branch circuit (along with the rest of
the branch circuits) and switched off the main breaker at the panel. The
branch circuit is a dedicated 15-amp circuit that feeds the one outlet
into which the ISOBAR-4 is plugged.
Once the power company was through reconnecting the power to my house, I
turned on the main breaker and then turned on each of the individual
branch circuits one at a time.
I didn't go into the room where my Photoshop computer is set up, and
didn't turn on the UPS.
The UPS apparently switched itself on when the power came back & I think
maybe it was the UPS-Mon software that turned the computer on. It didn't
turn on the monitor, which is why I didn't notice it until I went in to
try to get the printer back on-line.

I fully agree with you.
I know several cases when my colleagues have lost their computers and
other electronic equipments when the power was coming back up.
That's why I've always been trying, both at home and at work, to unplug
all somewhat valuable electric equipment from the outlets when the power
goes down.
Surge protectors are somewhat helpful as well.

After some years of investigating damage attributed to power anomalies
during power restoration, it is my opinion that here in the USA, it is a
good idea to leave the power to the computer (and other electric units)
disconnected/off until power is restored and stabilized. I use drop out
relays and/or ups systems with computers.

Many (most?) desktops since probably late 1990s/early 2000s have an
option in the BIOS that enables starting upon power loss/detecting power.
I've used this feature for many years with the computer, monitor and
other related devices all connected to one surge protector. With a
flip of a single switch you turn on all of them and have the computer
booting up.

've been bringing network resources up as I need them and finally got
around to the printer next to the Photoshop computer just now, I found
that the computer was already switched on. Hadn't noticed it because
the monitor was still turned off.
Since I didn't switch it on, what did?
