Yellow colored USB port on Thinkpad X220
What does the yellow-colored (not fully yellow but with a piece
of yellow thingy) thingy in the Lenovo X220 signify? Is it a
USB 3 port or it means the power is still on despite the laptop
is powered off?

So the laptop does not need to connect to AC power to have this yellow
USB port to be able to charge external USB devices?
And if it's connected to AC power, some sort of configuration is needed
for it to be able to charge external USB devices, did I get this right?
