LED Case Lights

I'm having a problem figuring out which LEDs go where on my motherboard. I actually think the case wasn't designed for this motherboard so I'm just stuck, but if someone could help me figure out a trick to get them to work, I'd appreciate it.

Motherboard:

Case:
http://www.chieftec.com/products/Workcolor/Dragon.htm
(It's the silver one and mine has a sidepanel window)

If anyone has any info at all on how they got there setup similar to mine to work, please tell me, I'd like to get those damn LED lights to light up!

Remember that LED stands for Light Emitting Diode ( not little electronic device as my fiance likes to say to taunt me!). Diodes only allow current to flow in one direction, they're basically one-way electronic gates. If you put the plug onto what you think is the right header and nothing happens, turn it around. The Positive and Negative wires are probably swapped and the diode is blocking all current instead of letting it flow and giving off that pretty byproduct -light.

What rebturtle said so very well.

I have the manual and I know where the LED plug is supposed to go and all that good stuff. Problem is the LED has more female connections than the motherboard and I've pretty much tried every combination I could with no light. I'm hoping someone has had a similar situation and found a way around this!

Okay, I've seen this before. Your case has 3-pin connectors (even though it only has two wires and the center pin is empty), but your mobo has 2-pin headers for the Power & HDD LEDs. The newer boards often help you out w/ this issue by providing two completely different sets of headers. Unfortunately, yours isn't that diverse. Your options are to either head to an electronics store (or dig up a compatible case you can steal parts from) to get new plugs for your case & start soldering, or to try to use something like a Dremel to (<i>very</i> carefully!!) cut down the (empty) center hole in the plug and render it into two seperate single plugs - similar to the ones you see for external USB ports in the newer cases. Other more complicated or costly options include making some kind of adaptor or buying a new motherboard/case. I hope one of the first two will work for you.

As a general rule the plastic connectors on the end of the LED wires indicate pin 1 with a little arrow and usually the coloured wire is pin 1. This will allow you to allign the connector with your mobo correctly. If you have 3 pin connectors with 1 blank you can take the metal pins out with a needle and slot them next to each other in different combinations until the 3 pin connector goes on to the board without getting in the way of another pin connection. Or you can cut down the 3 pin plastic bit to 2 pins using a craft knife.

It is very dissapointing that there wasn't a standard made years ago for this so that the case LEDs just came in 1 big connector that you could plug on to your board - like a floppy drive sized thing.

Ok this is what is on my motherboard. Keylock which has 5 wires, speaker which has 4 wires, reset with 2 wires, g-sw with 2 wires, ATX-SW with 2, G-Led with 2, and HD-LED with 2. My case has two lights at the front and neither will light up. Keylock has a Ground, Keylock, LED Power (-) or Standy Signal, N.C., LED Power (+). I know that has to be where it goes, but the case led connector has only two holes which are both together, I assume that i have to get the LED Power (+) and the LED Power (-) plugs detached in order to put them in there corresponding areas.

That's the Keylock:

LED Power +
N.C.
LED Power -
Keylock
Ground

So how could I fix this problem, splicing the connector would have to be the solution...but how do I go about doing that? Any input is appreciated! Thanks!

My dad and I have encountered this problem with some old MSI boards and skyhawk cases I have used. Just cut the plastic where the middle pin WOULD be. White/black wiring generally denotes the negative lead and greed/red/blue wire is the positive lead. So just find out what pins on the mobo are for the LED and switch em until it works! If not then I'd assume your LED is busted or your mobo is :p

So you are using a case with a lock on it are you? I haven't seen those for a while for home use. I suggest that unless you really need to lock the case so nobody can use it you should not bother connecting the keylock and just connect up everything else.

I have a Dragon ATX Case from Chieftec. It don't know what you mean by a lock...the only lock it seems to have is the lock on the cd rom drives, the power button and the floppy drive if you actually use the key which I don't. But all I'm trying to do is get those led lights to work, it is on the "Keylock" designated on the motherboard. I'm sort of confused on what you mean by Keylock though..

Forget all of this nonsense about the lock headers. That's for old cases that had an actual, phisical lock on them (I'm fairly certain of this. Correct me if I'm wrong guys). You want to hook up the Green LED two-prong plug to the two-pin power LED header on the mobo. Then connect the HDD (Hard Drive) LED two-prong plug to the two-pin HDD LED header on the mobo.

the keylock prevented the computer from booting.
