Dell Diagnostics Error Code
My notebook is Inspiron 1564, I bought it 1 month ago. Everything of the notebook works well except the webcam integrated. I try to reinstall software and driver but it still not works. I used Dell Diagnostics to check the problem and discovered some error code here:
Error code: 6600:0120

Hi,
I'm getting the same error on my Dell Studio XPS 1340 laptop while running the Dell diagnostics CD.
Error Code: 6600:011F
Msg: USB_Device - Unsuccessful enableBist command
I was wondering what the end result was? Was any hardware replaced and if so, what? I'm trying to decide what to do now if I should I get it repaired or replace it.
Thank you in advance.
- Will

Contact Dell Support to get help with a problem on a new computer. Try this if you haven't already--type Webcam in the Start box and open Dell Webcam Central to test the webcam. Contact support if it doesn't work. The webcam should work when you start a program that uses it like Windows Messenger, Skype, etc
