Did your IML log anything interesting? It may be more useful than trying to decode the motherboard blinkenlights.
Rarely, I'll have a weird thing like a server rebooting for no apparent reason, and IML didn't log anything, Windows event logs are blissfully unaware, etc. I guess the lights might have provided some insight, but probably not.
The only time I've ever paid any attention to the MB lights are when it won't boot at all, and even then, the front-panel indicators are usually enough. Only once or twice have I had to pop the lid and look at the actual diagnostic lights to get a better idea of what's happening. So I call those a "last resort" type of thing.
