Install S3 Sleep light on Gigabyte motherboard

My computer case has only 2 Pins for power LED.
Currently when I put the computer on s3 standby, all front panel lights turns off as well.

I want to either replace the power LED with a dual color or add another sleep led.
But problem is, when in s3 mode, I couldn't get a LED working in any "Power_LED" or "MSG".

I tested the voltage with a multi-meter and voltage appears to oscillate between 0v and 1.5v  
(approx).

Am I missing something or is there a special way to connect these or is there an additional  
circuit required?

Motherboard: Gigabyte GA-k8VM800M (rev2.0).
O/S: Windows XP SP2

The only connectors relevent to power are:

1) Power_LED
    Pin 1: MPD+
    Pin 2: MPD-
    Pin 3: MPD-

2) MSG(Message LED/Power/Sleep LED)
    Pin 2: LED anode(+)
    Pin 4: LED cathode(-)

All common gigabyte motherboards have the same pins I think.
Also I want to know how to work the "Message" LED working, that is to get messages, if I am  
correct.

Thanks.

I have the same issue with my gigabyte ga-p35c-dsr3. The msg led will be off in s3 mode and blinking in s1 mode so I don't think its posible on the msg led or the power led

probably in S3 no power is fed to any leds, in order to save power -> you can try to contact Gigabyte for this
>>   tested the voltage with a multi-meter and voltage appears to oscillate between 0v and 1.5v  <<  that is a normal voltage for leds (works from .7 V and higher)

I do not think 1.5v is a normal voltage for a LED as this voltage is present even if the computer is shut down. Also I have to mention that  the current (amperage) seems to go down when put to standby mode as well.

I wonder why I couldn't find this problem reported in any forum?
Can any expert who had assembled a Gigabyte m/b can help me?
