USB 2.0/1.1 Ports
USB 3.0 Port
Powered USB 3.0 Port
These USB ( Universal Serial Bus ) 2.0 compatible ports (USB 2.0 is fully USB 1.1 compliant) are
for low-speed peripherals such as keyboards, mice or scanners, and for high-speed peripherals
such as external HDDs, digital video cameras or high-speed scanners etc. Devices can be
plugged into the computer, and unplugged from the computer, without the need to turn the system
off (if the power rating of your USB device is 500mA or above, make sure you use the power
supply which comes with the device).
The USB 3.0 ports are denoted by their blue color; USB 2.0 ports are colored black. USB 3.0 will
transfer data much faster than USB 2.0, and is backwards-compatible with USB 2.0.
Note: The powered USB 3.0 port (see Figure 1 - 13 on page 1 - 23
)
may be toggled on /off by
means of the Fn + Power Button key combination. When the powered USB port is on it will supply
power ( for charging devices only, not for operating devices ) when the system is off but still
powered by the AC/DC adapter plugged into a working outlet, or powered by the battery with a
capacity level above 20% (this may not work with certain devices - see page
8 - 12 ).
Note: This function is designed to help charge USB compliant devices , but is not designed to
allow their operation .
