I have purchased a Lenovo Thinkpad Edge 15". Recently, I have experienced problems using my integrated camera with Skype (i.e. the integrated camera is detected but does not display anthing and the green light does not come on).
The integrated camera passes the "capture to screen" and "capture to file" tests from Lenovo ThinkVantage's Health and Diagnostics.
Therefore, I presume the problem pertains to the camera's driver but have had no success after uninstalling and re-installing a variety of drivers.
