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

I haven't seen a laptop that had this option. All my desktop boards do and flipping the switch on the wall sends power to all the machines and they all bootup, but any machines I built with laptops require the laptop to be powered on by pressing the power button.

When you think about, that makes sense. The power on after power fail hails from server-centric computers. These types of machines have features to maximize up time.
Laptops are for a different market and hence, it doesn't logically make sense to have that feature.

Not to mention the fact that since they are laptops they pretty much always have power supplied since they run on batteries! ;)
leapinlew:
yeah, but why not add the feature or more likely, why remove it?
Besides, whats a server nowadays? A virtualized piece of software which could and often does easily run on a laptop.
SavannahLion:
Why is this even a discussion? The whole "virtualized" business is just marketing. Servers, and their requirements, are very real and very distinct from those of laptops. Businesses have invested billions in massive systems consisting of hundreds or thousands of headless boards interconnected together running off of multiple power sources. The fact you can buy a board for a 100 quid with some of the big iron or farm features is just a byproduct of the SOHO market. Seriously, when did you find a need for ECC RAM in anything you built for home or any arcade cab?
Laptops and their ilk are clearly from the other direction. Things like headless operation isn't even an option (not in my laptops anyways) because they're not expected to operate without their built-in screens. I have rarely seen laptops that are built like desktops meaning that they're not meant to extensively modified by the end user. In other words, no laptop manufacturer designed their laptop knowing that leapinlew was going to build a cab out of it.
Servers are designed for maximum up time and horsepower. Laptops are designed for portability and power preservation. Given current technologies and business demands, those requirements have mutually exclusive demands. I have no doubt we'll see more and more convergence of the two schools as the technology improves, but for right now... well... there are other tricks you can do. :dunno
In any case, while hacking my own laptop, I did note some spots that, now that I think about it, would make it reasonably easy to add in such a feature to a laptop. I can't imagine any other laptop being more difficult than what I found. If you wish, we can knock some ideas together and see what sticks.

Seriously, when was the last time you seen desktop ECC RAM offered for sale?! :lol

It's kind of like a dildo. You won't know where to get one unless you're kinky that way.
Probably the last time I went to a store to buy pc components. Online or direct is where it's at.
Frys
Newegg
Though, anyone buying ECC for any decent operation would likely purchase it on contract direct. So pick the manufacturer, they'll have it.
But neither is my point, my point, should you fail to see it, is not every feature will be found all the way down through computing families even if individual board components support it. Those that do, will have the demand for it. Power on is one, RAID (at least partially) is another. ECC has no market outside of data critical computing, doesn't help price are grossly inflated. Meh. That's life. Hot swap has been fulfilled to a degree but I've yet to see internal hot swappable UPS/PSU, RAM, or CPUs.
