Having a shortage of power sockets, I wanted to charge my phone and my Thinkpad (X130e) by charging the notebook directly and the phone via USB. In the UEFI settings menu, I have enabled both "Always On USB" and "Always On USB Charge in Off Mode". The former's description claims that with it enabled, the notebook will charge external devices even when turned off. The latter claims the same but specifically for iPads, iPhones and Blackberries.
It doesn't work when I plug in my Android-based smartphone (an Xperia Neo V). Is it supposed to work? If yes, why not, if not, what might be wrong?
