I've seen this asked a few times, but I couldn't find a definitive answer.
I'd like to power on my mame cab with one switch. That will turn on the
monitor and the PC at the same time. Anyone know how to do that? I
remember seeing something about hacking the power supply so that whenever
their is AC fed to it, it will turn on the computer (i.e. whenever you plug
it in)

Follow the power on switch from the computer face plate back to the
motherboard. Locate the power switch jumper and jump it out. Being always
connected won't hurt any components on the motherboard.

If you don't like that idea, look in bios under power management settings
and look for settings in there. Most motherboards have a auto-power
function setting like ( what to do when power is interrupted: stay off or
restart) Most all computers are set to stay off requiring you to hit the
power button @ start-up.

The green wire on an ATX supply is what's grounded to fire it up, same as
the power-button so jumping out the power button does the same thing.

You don't have to scroll down far at all to find a thread called ATX power
supplied PC's. See responses there.

well this depends if your talking about an atx power supply or an at power
supply.
With an at power supply you can simply use the top connector above the power
cord. This is a swiched outlet, used for plugging your monitor in in the
olden days of computers. This is a business machine connector, and to use it
you will either need to buy a power cord with that end on it, or take apart
your power supply and solder your monitors power cord on to the back of the
top connector (the outlet, not where your power comes in).

This is how my mame machine is hooked up. I just have to hit the power
switch for my pc and Volia! The monitor is on and the pc is on too!

By the way if you don't know the difference between AT and ATX power
supplies the simple way to tell which you have is.

1 If you have one large square connector with 2 rows of 10 pins. Its an ATX
2 Or if you have 2 connectors each having a single row of 6 wires. It is an
AT power supply..

Almost all newer power supplies are ATX

Try this, http://www.smartstrip.net/. It's what I use and it works great.

i don't know, but i never felt this was a big problem. The reason is
that the monitors i use automatically shut down when the pc is off, so
there is no need to do anything to them or even ever turn them on off.
i just leave them on, and when you turn the pc off, they go off by
themselves.

about the turning the pc on and off,,, i do nothing to solve that
problem too. ok, maybe it's not so fancy, but it's easy... i just
point the pc to the front of the cabinet and make sure the shelf/pc is
positioned so that the on off button is right near the coin door when
you open it. therefor, to turn the pc/cabinet/monitor on, all i do is
unlock the coin door and push the button that is right there....

yes, not too ingenious or exciting, but it's easy and another thing,
it makes things so that whenever you want to swap pc's around, you
just do it.

If your computer will shut itself off upon exiting windows you can do
what I did and add a 12V relay to a power strip and power the relay from
12V in the computer. Use the power strip to provide power for
everything. (Except the computer :) )
Powering up the computer will bring everything else to life.

Or you can control everything from the power strip switch and leaving
all the individual power switches on.
I have been using that approach on my family computer for many years
without any damage to the monitor or computer.

This might seem a bit late in the day... but some BIOSes that support
power-off after shutdown also support single-key power-on; my keyboard
has "wake/sleep/power" buttons on them.

My ATX power supply also has a switched output, powering both speakers
and monitor. Hence, by hitting one keyboard button, I can power up all
three in one go.

(Unfortunately, I found that hitting several keystrokes can cause the
computer to lock up, too - I think they call that a BSOD...)

Why not just plug them all into a Surge Protector and just turn that
on and off? Can have it turn on the PC, speakers, monitor, lights,
etc...

Aside from the damage you might do by not properly shutting down a
modern OS, there are power-on concerns as well (I'll assume here that
you're referring to a DOS box where shutdown isn't as important an
issue).

The issue is that modern motherboards and power supplies are a bit too
smart for their own good in this regard. Turning off a power strip
connected to a PC makes the motherboard think there has been a power
outage. It then refuses to come back on again until the user forces the
issue (by holding in the power button for a few seconds). This keeps a
system from cycling on and off over and over again during a storm, for
example.

Personally, I prefer the "bad-old-days" of the AT power supplies and
dumber motherboards. Let me deal with the power outages myself! Or at
least give me the option of doing so (my motherboard has no "power
failure" or "power on" options that I can configure). But oh well...

As I've posted before, the solution that I'm using (which is a very good
one, IMHO) is the Smart Strip: http://tinyurl.com/yq3wr. I've done what
the first reply suggested: I have a momentary contact switch hooked up
to the power on pins on my motherboard. This activates everything else
in the cab via the smart strip. Then I have my front-end detect a
special key press ('5' and '6' together -- both of my coin door buttons)
that runs a shutdown executable. Once the OS finishes shutting down,
the smart strip shuts the rest of the cab off as well.

Sorry for the repeat of material here (I hope I'm not feed a troll!),
but I thought that perhaps the problem being solved might not have been
well understood.

"Chuk" <ch...@ourcade.com> gyrated his joystick in a pattern that spelled
out:

I was mentioned before that if you jumper soft-power switch input to ground
that the PC will come on automatically on power applied. I posted a circuit
diagram using a capacitor recently which could do the same thing. My mother
board has STR (Suspend to RAM) which is sweet. When I power it up, it loads
the entire machine back to desktop in about 10 seconds. Draws a small
amount of current to maintain the RAM though, so it must stay plugged in.

I don't mean just turn off the plug while the PC is still running. I mean Exit the front End, do a
Start Shutdown, then flip the switch. Some PCs you can set in the BIOS that when they get power
they automatically turn on which woudl mean you turn on the Power Strip and the PC, Monitor, etc
would al come on...

OK. Then what caused the OP problem for me was that my motherboard doesn't
provide me with that automatic turn-on feature. In such a case, a simple
power strip solution won't work.

Has anyone tried one of these...

http://www.bitsltd.net/smartstrip/home2.htm

It claims to shut off some switched outlets when a control device (like a
computer) is turned off. Best of all, no wiring.

I'm going to try one in my cab.

They have been reviewed over at www.retroblast.com, and Kevin @ Retroblast
is reviewing newer versions of these already...

Thanks,

I recently installed one of these in my cabinet. What I did was mounted a
new arcade button on the side of my controller(Slikstik) and hooked the 2
power wires from my computer to the button. Then plug everthing else into
the smart strip. When you hit the button, everthing comes on. The only thing
I had to put a second arcade button for was my tv. I hooked the 2 wires to
the circuit board where the switch is. The tv needs a momentary contact to
come on. I suppose you could wire a relay and plug it into the Smartstrip
and eliminate the second button. But it works great and the buttons look
good on the controller.

I use house wiring in my cabinets. The power plug is switched though a
conventional wall switch, and on from there to a conventional duplex
outlet. PC and TV plug into this outlet.

You'll need to jumper your PC supply to power on automatically, if
it's an ATX. And of course, you'll need a monitor/TV that retains
settings when completely off.

You need to run pin 14 (usually green) to ground (usually black: pins
3, 5, 7, 13, 14..17).

I used it and it works beautifully for me. Since my motherboard has a
keyboard press on feature, all it takes is a 2 button combination on
my SlikStik and the whole cabinet turns on. Another 2 button
combination turns it off.
