Charging a USB Device
You can charge a USB device even while your VAIO computer is off, in Hibernate mode, or Sleep mode by enabling the USB charging settings.
The USB charging settings are disabled by default.
-
Click
(Start), All Programs, and VAIO Control Center.
-
Click Power Management and USB Charging Settings to enable the settings.
-
Connect a USB device to the USB port with the
mark printed around it.
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.
Note
-
With the USB charging settings enabled, power consumption when your VAIO computer is off or in Hibernate mode or Sleep mode increases because the USB port supplies power 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.
