In the power options of my Lenovo T61 there is an option to keep power to the USB even when the computer is shutdown/in standby. With the option turned on and the computer off, I plug my iPhone into the USB but see no sign of it charging. I'm sure the "Always-ON" port works because it lights up and spins my WD Passport hard drive without a hitch. Odd because I would assume if it was a voltage problem the power to spin up the USB hard drive would definitely trump the power it takes to charge the phone. Anybody have an idea? Thanks.
