SoftPower, HDD LED, and Power LED connectors...
Posted: Thu Dec 02, 2004 5:29 pm
All,
Well, after a while of not touching it, I finally decided to play with that old Compaq Athlon system again. I figure if I can figure out the wiring of the button panel, maybe I can put in a true standard board, and just make my own connectors to plug the button/led board to the header pins for the power led, hdd led, and power switch.
There's 6 wires, and just the three items, so I'm figuring this should be easy.
Right off I figure pins 5 and 6 are for the power.
It seems that pins 2 and 3 are for the HDD LED, because disconnecting either one of them seems to render that LED nonfunctional.
However, for the Power LED, it seems only pin 1 does anything! Is it me, or does that seem strange? I figured removing the wire for Pin 4 should disable something, but it doesn't!
Does this seem normal? I'm trying to figure out how/why this works the way it does.
