A quick-ish Q for those more knowledgeable in these things than I... Case has power and a reset button... what I want to happen is: Press power button - pc turns on/off press reset - nothing happens hold reset, press power button - PC resets ^- simply put, is that do-able, and if it is, how would I need to wire things up?
You have a limited number of actions you can set up for the buttons in Windows Power Options but I don't think you can re-wire them to do what you want.
You could make a small circuit with a relay / solid state relay or transistor to do what you want. Edit: To expand on that a bit, for a relay you would run the wire from the power button through the normally closed contact of the relay to the power button connection of the mobo. You would run another wire from the power button through the normally open contact of the relay to the reset connection on the mobo. The reset button would power the coil of the relay. Depending if the coil is on or off the power button would act as reset or power button. You could leave out the relay if you get a double pole switch for the reset button
As all ready stated, no. Why do wish the such functionality? Knowing this could help yield possible alternative solutions simpler than building custom circuits. Are you looking for extra protection on the reset to pervent acidental reset? If that is so then you could wire two button in series for reset (without using the power button). Or you could use a protective cover such as a molly-guard.
It's more of a 'why not?' than a 'why?'... theshadow2001 seems to have understood what i want best... i'm guessing you mean something like this [which is kinda how i pictured it in my head] crappy excel diagram ahoy: Switch B [reset] being the double-pole... unpressed the signal goes to the power switch header, pressed it goes to the reset header...
I think you have it. The following is based on a couple of assumptions. 1. You are using a double pole switch with a normally open and a normally closed contact, not a relay 2. The same plus header can be used for power and reset. This is how I would draw it (ms paint For the win!): The C shaped things with a line coming out on the switches just represents a push button. The red box indicates switch two in its entirety. Switch two has a normally open (N.O.) contact and a normally closed (N.C.) contact. When switch two is pressed, it closes the N.O contact(on the left) and opens the N.C. contact (on the right). The dotted line represents a mechanical link between the N.O and N.C contacts of switch two. The dotted line is not an electrical connection, purely mechanical. When you press switch one. A path is created from + to - through to the power header. When you press switch 2 the path to the power header is broken, but the path to the reset header is now made, so when you press switch one and switch two at the same time, a path is created from + to - through the reset header. If you don't have the luxury of using a double pole switch as per the diagram and can only use the switches that come with a typical PC case, this diagram can be adjusted slightly to use a relay instead. I hope I've made this clear and not confused things.
Now that's a proper modder's reason. Only issue with this schematic is if you want to rest the computer you must push switch two first, otherwise you'll power down the computer.
That's fine with me... tbh i only use the reset button when the pc is completely unresponsive, and i'd rather not do the button hold down to force it off...
would need to know the motherboard front header pin out has a reset ? and are using 2 switches or 1 switch ?
