I just got a more or less fully loaded T400s to test out. I notice there is a yellow usb port on the back with a battery icon right next to it. What does it mean? I can charge another battery from that port? Port support more power? any clue?

Another useful feature of the ThinkPad T400s notebook is its Always On USB Mode. This is available on the rear USB 2.0 port, and can be enabled through the BIOS. It allows the T400s to charge USB devices (such as a BlackBerry, iPod or iPhone) even while the laptop is switched off. There is one caveat: the notebook needs to be plugged in to a power outlet. That means it's not as good as Toshiba's Sleep-and-Charge USB ports, as it can't charge a USB device while you are on the road.
