Can a PC be set to boot up upon receiving stand-by power?

marketing? I don't know what kind of IT work you do, but many of my laptop users use virtualized servers to run tests, sandboxed apps, etc.
You're right in that I don't know why we are having this discussion. I just wanted to know why a laptop wouldn't have the option to power on after AC power loss. You know, sometimes the power is out for more than 4 hours and when a laptop turns off the only way to turn it on is to press a button.
All I'm saying is, it would be nice to have the option. I didn't go on a tirade on what a ridiculous notion it is.

Don't most pc's have a boot from network option in the bios?
I assume that you could send a small amount of current to the
ethernet port to get a notebook pc to boot from standby, right?

wiki copypastea of the WOL protocol cause i'm lazy.
--- Quote ---The magic packet is a broadcast frame containing anywhere within its payload 6 bytes of all 255 (FF FF FF FF FF FF in hexadecimal), followed by sixteen repetitions of the target computer's 48-bit MAC address, for a total of 102 bytes.
Since the magic packet is only scanned for the string above, and not actually parsed by a full protocol stack, it may be sent as any network- and transport-layer protocol, although it is typically sent as a UDP datagram to port 7 or 9, or directly over Ethernet as EtherType 0x0842.[7]
A standard magic packet has the following basic limitations:
Requires destination computer MAC address (also may require a SecureOn password)
Does not provide a delivery confirmation
May not work outside of the local network
Requires hardware support of Wake-On-LAN on destination computer
The Wake-on-LAN implementation is designed to be very simple and to be quickly processed by the circuitry present on the network interface card (NIC) with minimal power requirement. Because Wake-on-LAN operates below the IP protocol layer the MAC address is required and makes IP addresses and DNS names meaningless.

OK, back to the question at the beginning of my post...
Good news!! I found the solution. This may not work for everyone, but it will work for my computer BIOS configuration:
Luckily for me, my BIOS allows the PC to auto start after it looses AC power. Not just if there is a power outage but if I “unplug” the computer from the wall and then simply replug it in.
Under “Power Management/AC Recovery” I set it to be ON, which means that the system powers on after AC power is restored.
I tested it a couple of times after doing a normal shutdown of Windows. After the computer shutdown I then unplugged the computer, counted to 10 and then plugged it back in. Boot right back up automatically without me having to push the power button on the computer. Worked like a champ.
So I don’t think a special switch is even needed now. I was ready to rewire the start switch to my computer.
All I need now is a remote switch to power a smart power strip where my computer is the “Master”.
Belkin Conserve Energy Strip
OR
The “SUG7” powerstrip with remote from Bits Limited:

My computer will now boot up once it receives power from the remote after sitting in a non-AC power state and then in turn will power up the monitor, speakers and marquee lights which will have already been “turned on” and are just waiting for power.

MTPPC:
Don't buy the belkin. If your computer keeps USB devices powered up, the belkin will not behave consistently and their is no adjustment like on the smart strip brand. I think that SUG is not necessary. I think you want a scg3 and then just extend your PC powerbutton to an arcade button on top of the cabinet.
