My aspire 5516 web cam is not working

Have you installed Service Pack 2 for Vista. It fixed a lot of files and included third party support. That was the only way I could get it to work with my HP equipment. This may or may not resolve the issue.

It will be necessary to install additional applications in order to use the webcam.
To test the webcam under Windows XP, please follow these steps:

1. Go to Start, All Programs, then Windows Movie Maker.
2. On the left side, click the link for Capture from video device.
3. Select Next throughout the set up, making any file name changes or setting changes if desired.
4. On the Capture Video screen, click on the Start Capture button
5. You will see the video on the right with a time count up
6. When you are done click the Finish button
7. Click the play button on the video clip, or drag the clip to the Storyboard below.

Call the tech support number provided with the warranty flier. They will ask for the SNID and they can tell you if your model has a web-cam or not. Even if there is a port at the top of the monitor, there may not be one installed.
