  • Last thing until it works...need auto startup!

    I have an ATX motherboard and there is not option to turn on the power after power failure or anything so I need some circuit to auto start the power when the car is turned on. I don't want to run another switch through my car so does anyone know of a WORKING way to do this. I've read many thigns and tried many different circuits but none seem to work right, they either reset after a given time or don't work at all.

    Not tested, but should work, and has the benifit of being simple. Use a relay with a two way switch (SPDT for the elecy people), connect the power good wire from the ATX to the relay coil along and the other end to ground. The connect the relay switch across the reset button so that, when the power is on the switch is open, and when it's off the switch is closed.

    This should automatically restart the computer if the power dies.

    As I said not tested and off the top of my head.

    Total re-design underway: on the whole progress is very slow as the car is taking up too much time :)

      I've tried so many things...if I connect the "power on" to ground the ps turns on but it does not post...

        What brand of MOBO?
        Maybe look for another bios
        If you come out talking sh1t don't try to turn around and wipe you azz.

          if you are using an ATX power supply connect pin 14 (the green wire) to any one of the black wires.

                jboy mentioned to you maybe getting another BIOS. Is that a feasible solution for you? Take a look at this page:

                http://www.esupport.com/biosupgrades/why.cfm

                They sell BIOS upgrades and one of the features their BIOS has (according to their page) is instant booting. I have personally never used their services, so I couldn't tell you how (un)reliable they are. Also, I can't seem to find a prices page, dunno how much they would charge, but hey, if you really want your PC to boot automatically.

                Anyway, hope that helps. Good luck.

                BTW, there's a few companies that offer this kind of service, this is the first one that came up in a search.

                  Have you considerd seraching the Hardware and Power Supplies forum? This has been covered several times, with circuits based on the 555 posted in almost every thread. Not sure if you have tried any of those circuits, but I haven't heard any complaints. All you need is a timer to momentarily trip a small relay to pulse the "power on" pins. NOT complicated.

                      All you need is a timer to give one pulse to the "power on" pins...How exactly does it "not work"? What circuit are you using?

                        when I use the 555 it keeps giving a pulse so it resets the computer if it gives another pulse which will not work. If I use the timer that only does one pulse(mono something) then you have to trigger the circuit which requires a switch.

                          There are many 555 timer circuits out there on the Net. If you build one and connect the trigger input to the power switch, it should work. But it's been a long time since I worked with the 555.

                          My choice would be to find someone with a PIC programmer, grab a $2 PIC and a few dollars worth of support components, and write your timer program in code. Probably the cheapest solution.

                          Or you could get weird. Make the output of the timer also trigger a relay that cuts power to the timing circuit or the relay that triggers the power switch.

                            This works for me:
                            If at first you don't succeed.........
                            destroy all evidence you tried

                            for info on t6369c LCD or Presslab's powersupply check:

                              I can't find those parts at Radio shack so I came up with an idea, would this work. If I have an XOR the outputs are like

                              0 1 1
                              1 0 1
                              1 1 0

                              so say the first input is from the power good source, allways on so when I power the switch that outputs the one to a transistor which connectes the power switch to ground, then once the power is on I have the other input connected to 5v from something that only provides power when the psu is on, therefore shuting off the transistor because both inputs will be high.

                              Will this wokr?
