The Universal Serial Bus (USB) connector is used for connecting USB interface-compatible devices, such as a printer or digital camera.

By default, even when your computer is in sleep (standby) mode, the Always On USB connector still enables you to charge some devices, such as iPod® and iPhone and BlackBerry® smartphones, by attaching the 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 online help of the Power Manager program.

Note: Your computer is compatible with USB 1.1 or USB 2.0.
