I am still planning my carputer and if you've seen the pics posted in this thread here you'll see what I'm talking about when I mention activity lights. I think that this is what they are called.
Anyways since I am the proud owner of 2 Vaio laptops I no longer have a desktop computer. Why is this even significant? Because I don't have one to take apart to see just where those lights (led's)are wired and to what.
If I wanted 3 leds to indicate:
1) Power (on or off)
2) HDD activity
3) DVD ROM activity
where would I wire them in? I'm at a loss here. Is it as simple as splicing them into the appropriate (and I don't know which would be) line?
I have the exact thing on mine
Mobos have a header block.. 2 of the pins will be Vcc and Gnd for the LED.
If you are lucky theres a IDE1 and a IDE2 (which I have) and I have dvd-rom on IDE2 and HDD on IDE1 (best way to do it!!!) just wire on your LED's to that
as for power.. theres another 2 pin header for that
if you have 1 Header for IDE activity, or both on one cable.. try this
remove cover on CD/DVD-rom, unsolder the LED and solder on your wire.
I have also extended my power buton with this, power button does hybernate/power on
I used a FDD cable, cut it and soldered on my wired to that, and a bit of electrical tape over that.
I have extended it from back to front with some Cat.5 cable.
you can have a common cathode for all the LED's if you want.
