Computer turns on after a power outage (when power returns)

I have an APC surge arrest surge protector. It has 11 outlets. I’m not using
two of those.

It recently occurred to me that it might not be working properly because
after a power outage in my home, when the power comes back on, so does my
computer.

Shouldn’t my surge protector prevent my computer from turning on by itself
when my electricity comes back on?
There’s a green light lit up on it indicating ‘protection is working’.

A surge protector is an enhanced power bar with electonics to "filter"
out the power spikes (surge.) If the surge protector is still powered
on and the PC's BIOS is set to "power on after power failure", or
"resume last power state", whenever the power is turned back on, the
PC will start.

You are maybe confusing the surge protector with a uninterruptible
power supply (UPS.) UPSes are a different stul of devices where there
is a battery in the unit and the PC can read this unit power status
"codes." The monitoring of the UPS unit power status "codes" will
tell the PC operating system (ie: XP) to shut down because the UPS has
no power coming into it.

The surge protector has no control over your computer, it is likely turning
back on because of a BIOS setting, you need to go into your BIOS setup and
find the setting that controls what the PC does when power is applied to it,
you likely want the option to stay off, it is probably set to last state of
always power on.

When turn my protector off and on my computer turns on. Something tells me
that’s not right.

I think I found my BIOS Settings.

F2
Scrolled down to Power Management

Here are my current settings.

Suspend Mode S3
AC Power Recovery ON
Low Power Mode Disabled

AC Power Recovery was marked OFF I switched to ON then turned off my
computer. I tried it out to see if it did the same thing. It did. After I
switched AC Power Recovery ON, The computer still came on automatically when
I switched the protector on.

I don’t know. Something tells me my computer should not turn on just by
flipping the surge protector switch.

There’s two lights on the protector to indicate a problem. They aren’t lit
up.

the device is called a surge arrrest, so i'm guessing it's not a UPS.

That's the setting you need, turn AC Power Recover to off.

Last night I switched AC power recovery to ON. Which means when I was having
my problem it was set to OFF. If it was set to OFF why did I have that
problem?

Now it is set on OFF and I placed the computer power cord in an ‘always on’
outlet. No more problem. The computer stays off when I turn the protector on
and off now.

Which brings me to my next question.

Is it safe to have the computer power cord plugged to an ‘always on’ outlet?

'outlets controlled by the On/Off switch are not surge protected when the
unit is Off. The always-on outlets are always surge protected.'

Is that true?

Plug the computer into one receptacle of the AC eclectic outlet.
Plug the surge protector into the other outlet. Now you have the
exact same protection as if the computer was plugged into the power
strip.

There is nothing between those power strip outlets and the AC wall
receptacle. The protector circuit inside that power strip could be
removed from the power strip, plugging into the other duplex wall
outlet - and the electrical schematic is unchanged.

Those protector components connect to AC mains as if an AC light
bulb. There is nothing between AC electric and the computer - except
a 15 amp circuit breaker so essential to human safety.

What happens when a surge occurs? It confronts protector circuit
and computer simultaneously. So yes, if you are having doubts about
what it really does, then you are on track to learning some damning
facts. Power strip protector does not filter anything. Power from the
wall receptacle connects directly to computer via a power strip.

What is the difference between the 'always on' receptacle and
others? Others connect directly to AC mains and that 15 amp circuit
breaker via a switch. 'Always on' connects directly to AC mains via
the 15 amp circuit breaker.

It is safe. It's a matter of preference, some people turn of the surge
strip, some unplug completely, up to you.

thanks w_tom but that was a little long for me. short and simple works for
me. i'm a blonde, sorry.

thanks david. thou i think i'll leave my protector on and plugged to the
wall. something tells me if i turn the protector off when i'm not using it
AND it's still plugged to the wall, my things aren't surge protected.

i clearly need a surge protector FAQs. i searched APC.com and the net last
night. i couldn't find a basic guide. so thanks for your help.

computer.

Shouldn’t my surge protector prevent my computer from turning on
by
itself
when my electricity comes back on?
There’s a green light lit up on it indicating ‘protection is
working’.

Unplug computer from power strip. Plug computer into same duplex AC
receptacle used by power strip. Nothing is changed. With computer
powered from the other wall outlet, it is electrically connected as if
plugged into the power strip. All protection circuits remain exactly
same. Makes no difference which side of power strip computer
connects. Same protector circuit connects to both sides of power
strip.

APC, et al hope you don't learn that. They need you to believe that
power strip is some kind of 'magic box' filter device. Myths because
the profit margin is so massive. Taking a $3.50 power strip, adding
some $0.10 parts, and sell it for $25. Massive profit margin means a
niave customer is important.

As others noted, nothing in that power strip affects your computer
other than to turn power on and off. Computer connects direct to AC
mains when plugged into a power strip or when plugged into an AC wall
receptacle. There is no 'magic' inside that power strip.
