You can charge a USB device even while your VAIO computer is off or in Sleep mode by enabling the USB charging settings.
Change the settings while the USB device is disconnected from the USB port that supports USB charging.
If charging does not start even when you connect a USB device to the USB port that supports USB charging, disconnect and connect the device.
With the USB charging settings enabled, power consumption when your VAIO computer is off or in Sleep mode increases because the computer supplies power to the USB port even when a USB device is not connected to the port.
When the USB charging settings are enabled, you cannot use the remote wake-up function on the USB device connected to the USB port that supports USB charging.
Some USB devices do not support USB charging when your VAIO computer is in Sleep mode.
The USB charging settings are disabled by default.
