Webcam

My webcam and microphone are not working on my 1545 laptop. Its not detecting a microphone or webcam and they are integrated.

I have opened device manager and there is not a listing for imaging devices...

what do I do now?

1. Close any applications that are currently using the webcam (this may include web pages). Save and close any applications that you are currently working on as the computer will need to restart.
2. For best results uninstalling the existing webcam driver before installing a new one is recommended.
     To uninstall the existing driver, perform the following steps: 
   
   1. Click Start
   2. Right-Click Computer.
   3. Click Properties.
   4. Click Device Manager in the upper left-hand corner.
   5. Click Imaging devices.
      (When there is not a listing for Imaging Devices, Contact Technical Support)
   6. Right-click the Integrated webcam.
   7. Click Uninstall.
   8. Confirm the uninstall process by clicking OK.
   9. Once uninstalled restart the computer.
      (When the Hardware Wizard window opens after rebooting, clickCancel, then download and install the webcam drivers).
3. The Webcam Driver can be found under the Input section and is listed as, Applies to: Integrated Webcam on the Drivers and Downloads page, for more information refer to Dell Knowledge Base article "How to Download and Install a Driver".
4. For best results the webcam software should also be uninstalled and reinstalled after the drivers are installed, for more information refer to the Uninstall and Reinstall the Webcam Central Software section.
