Disconnecting LAN cable
To disconnect the LAN cable, follow the steps below.
Make sure the LAN Active indicator (orange LED) is out before you
disconnect the computer from the LAN.
1. Pinch the lever on the connector in the computer and pull out the
connector.
2. Disconnect the cable from the LAN hub in the same manner. Check
with your LAN administrator before disconnecting from the hub.
Using the microphones
Your computer has builtin microphones that can be used to record
stereo sounds into your applications. It can also be used to issue voice
commands to applications that support such functions.
Since your computer has builtin microphones and speaker, "howling"
may be heard under certain conditions. Howling occurs when sound from
the speaker is picked up in the microphones and amplified back to the
speaker, which amplifies it again to the microphones.
This howling occurs repeatedly and causes a very loud, highpitched
noise. It is a common phenomenon that occurs in any sound system
when the microphones input is output to the speaker (throughput) and the
speaker volume is too loud or too close to the microphones. You can
control throughput by adjusting the volume of your speaker or through the
Mute function.
To adjust the volume or activate Mute, click start, point to All Programs,
point to Accessories, point to Entertainment and click Volume Control.
In the Master Volume panel, you can use the slide bars to adjust the
volume level or click Mute at the bottom of the panel.
