Asus Maximus Extreme - Manual (Page 32)

2-4 Chapter 2: Hardware information
5. Hard Disk LED
The HD LED is designed for indication of the hard disk activity. It blinks when
the data is written into or read from the hard disk drive. It stays unlit if there is
no hard disk connected to the motherboard or the hard disk does not function.
6. Power LED
The motherboard comes with a power-on switch as the standby power LED.
The switch lights up to indicate that the system is ON, in sleep mode, or in
soft-off mode. This is a reminder that you should shut down the system and
unplug the power cable before removing or plugging in any motherboard
component. The illustration below shows the location of the onboard power-
on switch.
