Reply With QuoteI was just reading some post and someone said to just solder the switch closed so its always on...will this work or could this cause an problem and blow the thing up?
I just got a motherboard and its a n ABit VT6X4, its a really nice board but it does not have an option for power on after power failure...anyone have any ideas on how I can get it to power on when I start the car without running another power switch?

I'm not going to say whether this is a good or bad idea.. but there's no reason to solder it when you can just short the header with a regular jumper. You can also cut the wires from the switch and twist them and tape or use a wirenut.

mp3car system is currently FUBAR and finances do not allow for a correction of that situation
Real computer hackers use a rotary cutting tool on their motherboard.
Alternatively short the switch with a relay and connect it to the starter motor relay, that way, when you turn on the ignition it should turn on the player.
And you say people actually pay money for M$ Windows?

Total re-design underway: on the whole progress is very slow as the car is taking up too much time :)
well I did not want to run another wire.
The ATX push button is supposed to be momentary, however that may work. You can also take the power on from the atx connector and wire it to keep the system always on, or biuld a small circuit with a 555 timer to provide a pulse.
I looked up the 555 timer but how can I make it so it only does that one pulse to start it..if it does another one it will restart the machine?!
I found this circuit, will this work for what I am going to do. Hook a transistor up to the pin on the MB so when it gets power it makse the switch in the circut attached. Will this work?
I can't find my little 555 book. You want a circuit that gives about a .5 second pulse then nothing else untill you remove power.
I just came up with a design using a relay on the normally closed terminals and it opens when the power supply turns on. This is the same as pressing the button until the computer turns on thus breaking the contact. This is wired up to turn on at ignition and stay on until shutdown no matter if ignition is on or off.
Seems to work great so far.
