boot

I want my computer to start automatically.
But I don't know how, I tried putting a jumper on the motherboard where the connection is for the on/off button.
But then the computer shuts down automatically since the button is pressed longer then 4 seconds constantly.
You cannot abort this procedure in the bios.
So taping the button down or putting a jumper on the motherboard where normally the wires are plugged in doesn't help.
Another computer I had did do restart everytime you plugged him in.
My plan is, I've got a infrared controlled block where the stekker goes in(where it gets electricity from) I don't know if stekker is english but well anyway it is the block where you plug in several stekkers...

You simply short cut the start-buttons pins, right? In my opinion you need a relay, which triggers the circuit only for a short time and opens it again, so that your pc doesn't restart again. Your chances are better to find out how such a relay-wiring can be build, if you ask directly in an electronics-forum.

Can't you do something in the BIOS? My PC has a setting for restart after power failure.

Yes there is something for that failures, but my pc doesn't give failures so it doesn't restart either.
About the relay that gives small pulses of electricity seems like an good idea.
Because you CAN configure the computer that if the button gets pressed shortly it won't do anything.
So that would be an option.
So now it is just a circuit that needs to be built that just goes open/close/open/close.
Since that is the only thing you do when pushing the buttom shortcut the circuit.
Anyway putting a jumper on the motherboards entry of the on/off button doesn't work the computer will shut down if you hold it down longer then 4 seconds.
I'll go and ask at the computer store tomorrow about how to do it, if they come up with bios bullshit then I'm going directly to the computer store and ask how to make this switch that goes on and off automatically.
Guess it uses a little battery on it's own and then ............blabla........
Thanks for the good idea by the way.

Easier:

On the "stecker" from the powersupply (PS2 style of course, not AT) you have usually a thin green cable near the middle of the "stecker". You connect this sense line with ground (Masse), say any of the black cables from the powersupply and thats that.

Actually its just the motherboard having to tell the powersupply to switch on and off and this way the powersupply is always on.

I learned this by using computer powersupplies for electrolysis...
