Annoying 4 second ATX button delay

I have never seen any reasoning behind the fact that you have to hold down the ATX power button for ~4 seconds for it to shut off if your computer freezes/you're in DOS/you're playing around with Linux/Unix/whatever... It drives me crazy, I find myself having to hold it down quite a bit. Anyway, I want to know if this would work...

Basically, I want to set the option on BIOS to resume after a power failure or whatever. Then, I want to cut the pin 14 and one of the grounds to the ATX connecter to the motherboard, and wire those together through a non-momentary switch that would be placed on the front of the case. Then I would have an ON and OFF position, and I could just flip it on and off like you could back in the days of the good old AT form factor.

Of course, I would leave the normal power button in place incase I needed it for something...

What do you guys think? Would it work? Could it possibly fry the CPU/motherboard/anything else?

Thanks :D
 
There is usually an option in the bios to set the button to instant off rather than the delayed off. I don't know what your motherboard is so I can't say for sure. Just look around in the power settings in the bios. Although you could also use your mcguyver solution if you really wanted to.

Thanks for the idea, my current MSI motherboard doesn't have that option, however I do have an IS7-E on the way, maybe that one will... I should probably find out before I start cutting up my case/power supply :p
 
flash your bios,

i've never honestly seen an msi mainboard without that option

there's also that little reset button, while the system is posting, power should be instant off
 
wow... you're gonna spend an hour or two to wire and build a switch to mod it to the front of your case just to save four seconds? personally, i think thats a waste of time

however, the way u describe the switch, i think it will work but i dont know if your motherboard may have problem [H]ard powering up like that, i think its more standard to use the front panel connectors/switch it may work, but dont come crying to me if you set your computer on fire or anything like that

why not design a switch that holds itself for 4 seconds and slowly springs back and replace the switch in the front? ... or maybe stick a lil gum between the button and surrounding plastic so it holds the button down for a few seconds more after you let go:D ..lol, jk, dont do that
 
Hmmm... yeah I have a MSI K7T Turbo 2, and Ive had many others... seemingly burnt out my recent K7N2 Delta ILSR... but they all had the instant off feature.... as was said you should update your BIOS and check
 
Mine issues a shutdown command to Windows as soon as it's pressed- or, in my case, the two wires are rubbed together.
 
Plug your PC into it's own power strip and use that to turn it off instantly.
