USB Port (3.0, on selected models / 2.0)
The USB (Universal Serial Bus) port is compatible with USB 3.0,
2.0, or USB 1.1 devices such as keyboards, pointing devices,
cameras, hard disk drives, printers, and scanners connected
in a series up to 4.8Gbits/sec (USB 3.0), 480Mbits/sec (USB 2.0),
and 12Mbits/sec (USB 1.1). USB allows many devices to run
simultaneously on a single computer, with some peripherals
acting as additional plug-in sites or hubs. USB supports
hot-swapping of devices so that most peripherals can be
connected or disconnected without restarting the computer.
USB Charger+ (on selected models)
The feature allows you to charge your mobile phones or
digital audio players while your Notebook PC is working
under system power on mode.
