This section explains indicator functions.

LED system indicators next to their respective icons glow when specific 

computer operations are in progress.

The DC IN indicator normally glows white when 

power is being correctly supplied from the AC 

power adaptor. However, if the output voltage 

from the adaptor is abnormal, or if the computer's 

power supply malfunctions, this indicator will 

flash amber.

The Power indicator normally glows white when 

the computer is turned on. However, if you turn 

the computer off into Sleep Mode, this indicator 

will flash amber - approximately one second on, 

two seconds off - both while the system is 

shutting down and while it remains turned off.

The Battery indicator shows the condition of the 

battery's charge - white indicates the battery is 

fully charged, amber indicates the battery is 

charging, and flashing amber indicates a low 

battery condition. Please refer to Chapter 6, 

 for more 

information on this feature.

The Hard Disk Drive/Optical Disc Drive 

indicator glows white whenever the computer is 

accessing the built-in hard disk drive or optical 

disc drive.

The Memory media slot indicator glows white 

when the computer is accessing the Memory 

media slot.

The Wireless communication indicator blinks 

amber when the Bluetooth and Wireless LAN 

functions are turned on.
Only some models are equipped with Bluetooth 

and Wireless LAN functions.
