USB Keyboard?

System power on by usb keyboard/mouse? - impossible or depending on mobo?

I think impossible, USB ports aren't fed 5V while system is off so KB and mouse would be turned off as well....... I haven't seen a board that has an option for this either. (I also haven't seen a lot of new boards, so maybe they're out there now)

Hmm, thanks for the feedback! - pitty Microsoft does not include a ps2 adapter with their retail keyboards. That really annoys me.

there is 5V in that port and I think it could be done easily by changing mobo design a little bit. I faintly recall I had a mobo a few years back where it worked

Yeah the PS2 port would do that I think but I'm not sure. The only thing that usb devices will do is wake a computer if its hibernating or something similar but it can't be completely shutdown unfortunately.

some motherboards keep the USB power fed even when off... i've actually got an older one with as Asus board in it i think that via USB keyboard can turn it on....

So it's not impossible... it's very much mobo specific i think

not many people use keyboard power up.....

have had such a board myself a couple of years back. Technology is advancing backwards fast. Now on a AM3 board things no longer work that were still working, on a 939 socket board, like HDD temperature under AHCI or keyboard power on.

i think they are taking the "green" stuff to the max.

shutting off standby power and so forth..

Usually a setting can be adjusted in the bios.. but i haven't really bothered looking or trying.... i use a power button the computer... not sure why hitting a keyboard is gonna make it any easier... actually it's more annoying considering a keyboard button being pushed accidently

..and once your power button fails you have no second chance like mouse/keyboard power on

I am used to keyboard power on (any key/password) since years

i've seen at least 5 times as many keyboard failures then i have power buttons..

the only reason i've seen a power button fail is due to punching it
