Yellow colored USB port on Thinkpad X220
Posted on 2012-12-26
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?

5) Always On USB connector
The Universal Serial Bus connectors are used for connecting devices compatible with a USB interface, such as a printer or a digital camera.
By default, even if your computer is in sleep (standby) mode, the Always On USB connector still enables you to charge some devices, such as iPod®, iPhone, and BlackBerry® smartphones, by attaching the devices to the connector.
However, with the ac power adapter attached, if you want to charge these devices when your computer is in hibernation mode or powered off, you will need to open the Power Manager program and configure corresponding settings to enable the Always On USB connector function. For details about how to enable the Always On USB connector function, refer to the on-line help of the Power Manager program.
You don't have any USB 3.0 ports on that model

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?
