Always On USB connector
The Always On Universal Serial Bus connector is used for connecting devices compatible with a USB
interface, such as a printer or a digital camera.
By default, even if your computer is in sleep (standby) mode, the Always On USB connector still enables
you to charge some devices, such as iPod
devices to the connector.
However, with the ac power adapter attached, if you want to charge these devices when your computer
is in hibernation mode or powered off, you will need to open the Power Manager program and configure
corresponding settings to enable the Always On USB connector function. For details about how to enable
the Always On USB connector function, refer to the on-line help of the Power Manager program.
