Scott Posted July 27, 2010 Share Posted July 27, 2010 With a push button latching switch, if the power is cut does it automatically turn off? Motherboard on a work PC isn't working with regards to the power circuit. I'm going to manually bypass it until we can get some sort of permenant solution (Motherboard came out when Jesus was a boy). I was hoping to use a latching push button switch but I don't want the power coming on instantly after a powercut (spikes etc). Ideally I want to press the switch to turn the PC on and if there is a power cut I want the switch to trip so that when the power comes back on I have to manually push the switch... hope that makes sense. Not sure if latching switches do this or whether I need a specialised one? Cheers Quote Link to comment Share on other sites More sharing options...

Scott Posted July 27, 2010 Author Share Posted July 27, 2010 Would I be out of order making a comment about being a tight scot and just say go buy a new pc You could mate but it isn't quite that simple The PC isn't mine, it is used for testing aero engines in the test facility I work in. It uses VERY specialised equipment including 2 ISA cards that are completely bespoke to this kind of work. The motherboard is now totally obsolete and I can't really do a proper search for one till I get home (Internet Security etc). Replacing the motherboard is an option, but I would need one with ISA slots and I would also then need to worry about the OS being compatible with the board. It is using NT4, any ideas if that OS needs a repair/reformat after new motherboard install? I know XP does but I've not had much call for NT4. If you can find me a GA-6VXE7+ motherboard that would be great Quote Link to comment Share on other sites More sharing options...
JustGav Posted July 27, 2010 Share Posted July 27, 2010 If it is an ATX power supply there is a Power-ON pin that needs to go up, wondering whether just tieing that up would work.... Quote Link to comment Share on other sites More sharing options...

It does bud. If I connect the green wire to ground the PSU fires on. I have to be careful with this equipment though. The Scenario is this.... There is a power out on the site, when the power comes back on it spikes like a bitch and because the power supply is wired on it blows the motherboard taking the very expensive cards with it. I need a latching push switch so that when the power drops, the circuit is broken within the switch. That way when the power comes back, spikes and all, it doesn't take the PC with it. Just had a chat with an RS salesman and it works as I thought. Just need to order a switch and the job will be done Quote Link to comment Share on other sites More sharing options...

Scott Posted July 27, 2010 Author Share Posted July 27, 2010 Put a decent UPS infront of it? That's up to the powers that be if they want to spend that sort of money. I have suggested a decent surge protector and the switch as a temporary solution, they are mulling it over just now lol. Needs a massive upgrade to be honest. The touble is the cards, no doubt the company who installed it all will want 10000's to upgrade. Quote Link to comment Share on other sites More sharing options...

Cost of a cheap UPs, roughly £100.... EASY business case for that one Quote Link to comment Share on other sites More sharing options...
