HOw can I do this on my laptop? I've an
Acer Extensa 4620. I want to know the settings for both Windows XP and Windows 7.
That model computer on Acer's website says that it has a webcam, which means it will also have a microphone that you can configure in Skype or whatever other program you want.
Windows 7 Control Panel Hardware and Sound Manage Audio Devices Recording Tab Set the Microphone device to whatever is tied to your webcam, to your default communication device. Configure your chat program to use this microphone.
Windows XP should be very similar...
