power on with cordless keyboard?

[NeoSolo]

I know there are some mobo with power on with keyboard function.
Does this work with cordless keyboard?

Thanks

To my knowledge, a cordless keyboard works identically to a corded keyboard insofar as what is supplied to the keyboard connector at the mobo.

Won't work. Catch 22. The receiver needs to be powered in order to receive a signal from the keyboard. If the computer is powered down, there is no power being fed to the receiver. I tried it anyway and it didn't work. Wish it would cause my box is hard to reach from where I normally sit.

Interesting. On my newer computer, my conventional keyboard is still on when the computer is off.(the lights are still on.) Of course it has to be in order for the keyboard to turn the computer on. And it does turn on the computer if you set it to do so in the BIOS (and not otherwise). I really can't see why the receiver on a cordless keyboard receiver would not be powered if an actual powered keyboard is.

OTOH if the receiver gets its power elsewhere, I can't see why it woulld be unpowered when the computer is off either.

IAC, I tried somebody's computer that has a cordless keyboard, and it doesn't turn on the computer when I press the space bar. O well, so much for logic. One more mystery added to the list of things I will never figure out. Possibly cordless keyboards are designed to detect the computer being off somehow, and to shut themselves off to save the batteries? But you can see there is no reason why a cordless keyboard could not turn on the computer if it were designed properly. The thing is, you can design a trigger that takes so little power to keep alive that you have almost the same battery life with it on as off. I believe remote controls, like for TVs, are generally designed that way.

I use a Logitech Cordless and it works fine.

Doomer, sorry, wrong. When a mainboard is enabled for Keyboard Power On, then the PS/2 port stays powered. Thus, the (wired) keyboard or the (wireless) transceiver has power. This or that kind of keyboard, power-on by keypress will work.
On a wireless keyboard, that means the keyboard and mouse are eating batteries all the time. Good idea?

I have the logitec wireless keyboard and mouse and the power on fuction works. The batteries (two AA) last for months. The ones for the mouse only good for a 3~4 wks. I use NiMH battery for them.
