Those of you who have a multimeter, can you please check if your charger has pins 2 and 3 of the USB socket shorted?
The USB Battery Charging Spec says:
Quote:
1.4.5 Dedicated Charging Port
A Dedicated Charging Port is a downstream port on a device that outputs power through a USB connectory, but is not capable of enumerating a downstream device. A Dedicated Charging Port is required to output at a minimum current of IDCHG at an average voltage of VCHG.

A Dedicated Charging Port is required to short the D+ line to the D- line.
I think the last point is what Sony used to decide whether to charge or not.
