You need a different LED to enable it to show two colours.
MSG/PWR (Message/Power/Sleep LED, Yellow/Purple):
Connects to the power status indicator on the chassis front panel. The LED
is on when the system is operating. The LED keeps blinking when the sys-
tem is in S1 sleep state. The LED is off when the system is in S3/S4 sleep
state or powered off (S5).
That's what it says in the book.
Now why does it put yellow/purple? What does that mean?
Normally LED needs two connector + and - ,
So how would u connect two led?
I think u would need to buy one LED that can change two colors, that is the only way the messaging would work?
