| 232290 | 2004-04-30 04:27:00 | The switch is fed 5V through a resistor (pullup) from 5VSB. That wire is a logic level. Pushing the switch shorts it, and gives a logic low level pulse for as long as you hold the switch in. It's that pulse which is needed to operate logic on the motherboard. The motherboard would "assert" a level on that pin 14 to make the PSU stay on. That would be high or low. I don't know which, but probably low. So you might need to link pin 14 to ground for it to work. I'd be inclined to take the 5VSB through a resistor to the high side of the switch. That won't do any damage. Shorting (or putting 5V on) the motherboard line to pin 14 might. |

| 232291 | 2004-04-30 11:50:00 | Have you tried unplugging the switch from the mother board and bridging the pins to start the computer, I have done this a few times and it works fine. This would tell you if the problem lies with the switch or the mother board. Rob ;\ |

| 232293 | 2004-04-30 21:46:00 | I used to work in a place where first thing in the morning we'd prop a fan heater up to blow on the tower for ten minutes otherwise the comp wouldn't start. Strange but True. :D |

| 232295 | 2004-05-01 12:18:00 | I'm sure it was a joke StevieRay but I agree with Jester - don't. Lots of ordinarily honest people think it is OK to make false insurance claims. And sometimes they get away with it. But it is still fraud. Honesty is a matter of integrity which each person has to decide for themselves. They may get away with dishonest behavior but they still know what they have done. Here endeth the homily. :D |

| 232296 | 2004-05-01 12:58:00 | The saga continues! I exchanged the reset plug for the power plug and it worked. Booted & shut down several times, got all embarassed because there was some looseness in the plug. Refitted the covers. It has refused to go ever since!!! I tried a new power unit but it was just the same. I will now try the resistor idea. Value for the resistor has been given from 4Kohm to 8Kohm. How critcal is this? |
