Lenovo Portable Computer User Guide
11
1. VGA port
This port lets you connect an external monitor or a projector to your
computer.
2. USB (Universal Serial Bus) ports
You can connect USB devices to your computer, such as mouse,
full-size keyboard and memory key, etc. The USB ports comply with
USB2.0 standards, which enable data transfer speeds 40 times faster
than the USB 1.1 standards. (The ports also support USB 1.1.)
Hint The USB device supports PnP (Plug and Play) technology,
which means you can install and remove the USB
device when your computer is on.
3. Air vent
The internal fan and louvers enable air to circulate in the computer
and cool the central processor. Be careful not to block the vent.
Note
When the computer’s temperature is high, the
computer will run the cooling fan automatically. The
cooling fan makes a little bit noise when it operates.
But that is not a malfunction.
4. IEEE 1394 port
You can connect an external device that supports IEEE 1394 to this
port for high-speed data transfer. Most digital cameras support this
technology.
