Hey. I have just got a new fancy computer case. It has a LED strip shining from top to bottom on the fromt door case. This connects directly to PSU molex connector (I have got this working fine). It also has an LCD display at the top which displays CPU temp, Fan RPM and Time of day. There is a connection from this which has " + H.D.D. LED " on it. I thought I plugged it into the right pins on the mobo but the LCD didn't come on. Then another connector coming from one red LED exists and I thought I plugged that into the right mobo pins but it doesn't light up (I assume the latter one was for HDD activity LED as the connector has printed on it " H.D.D. LED "). My mobo pin layout is shown below to the best of my ability.

Sorry no descrip for JFP2, but I know pins 2,4,6,8 are for speaker. In the manual it says 1,2,3 are for power LED.

Sorry for the long haul guys. I had the " H.D.D. Led " in pins 1,3 in JFP1 and the " + H.D.D. Led (from LCD) " in pins 2,4 in JFP1. One question, can I have the small case speaker on my case panel not connected, and the LCD connected, and have the LCD working? As the case speaker and lcd share the same circuit board at the front of the case and I wondered if the speaker has to be connected before the LCD would work.
Cheers.
