ACPI LEDS on P55A-UD6

[jojodancer]

What are those 4 LEDS? The manual does not say which color is which.

Page 23:

S3_LED
S0_LED
S4_S5_LED
S1_LED

When the power is off and I see red. When the power is on and I see green. What are the other two as well?

Good info and thanks.

But they don't tell me which color represents to which LED?

As far as I know when the the power is off, it is red.

When the power is on, it is green.

Ahh sorry!

I believe it goes from green to red, with orange/yellow in the middle. I do not have your board so I can't be sure, if you look closely they are labeled on the PCB.

S4/S5 = Red
S3 = Orange
S1 = Red (I believe, cant test if you want)
S0 = Green

Are you having issues or just wondering?
