Hi. One old PC of mine got a new HDD from an old PC which, on the other hand, got fried. Now, I installed the system and everything seems fine, only that there're those 3 indicator lights on the case - green, yellow and red (see image - sorry for the MS Paint action, but had no imaging device). See, I have several PC's with the same specs and the same cases at work, but none has the yellow light shining. I don't really care about the light itself - I mean it's nice to have something besides itchy red and green - but not the easthetical factor is here the point. Anyways... I understand that the green one indicates power supply and the red one indicates HDD activity. Long story, short said - what does the yellow light indicate? Thanks!
If you trace the wiring from the yellow LED, you might be able to find out what it's intent is and might be able to match it to the appropriate front-panel header. PC cases generally come with only 2 indicator LEDs, so the 3rd one is probably proprietary.
