Air Vents
The air vents allow cool air to enter and warm air to exit the Notebook PC.
IMPORTANT! Make sure that paper, books, clothing, cables, or other objects do not
block any of the air vents or else overheating of the Notebook PC may occur.
Microphone Input Jack (Mic In)
The mono microphone jack (1/8 inch) can be used to connect an external microphone or
output signals from audio devices. Using this jack automatically disables the built-in
microphone. Use this feature for video conferencing, voice narrations, or simple audio
recordings.
1394 Port
IEEE1394 is a high speed serial bus like SCSI but has simple connections and hot-
plugging capabilities like USB. The interface IEEE1394 has a bandwidth of 100-400
Mbits/sec and can handle up to 63 units on the same bus. IEEE1394 is also used in
high-end digital equipment and should be marked “DV” for Digital Video port.
2.0
USB Port (2.0/1.1)
The Universal Serial Bus is compatible with USB 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 12Mbits/sec (USB 1.1) and 480Mbits/sec (USB 2.0). USB allows
many devices to run simultaneously on a single computer, with peripherals such as USB keyboards and
some newer monitors 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.
