Hello Support,

sorry for the delayed response but it took a little time to dig deeper into this nasty problem. My observations were:

*) I already had the A22 BIOS installed

*) on the Dell website one can download two driver versions:

#) 1.02.02.0603 aka R189395 A01, see http://support.dell.com/support/downloads/download.aspx?c=us&cs=555&l=en&s=biz&releaseid=R189395&SystemID=PREC_M2400&servicetag=&os=WLH&osl=en&deviceid=16027&devlib=0&typecnt=0&vercnt=1&catid=-1&impid=-1&formatcnt=0&libid=17&typeid=-1&dateid=-1&formatid=-1&source=-1&fileid=259778

#) 1.08.01.0129 aka R258275 A07, this is the same version as the Windows Update site provides, see http://support.dell.com/support/downloads/download.aspx?c=us&cs=555&l=en&s=biz&releaseid=R258275&SystemID=PREC_M2400&servicetag=&os=WW1&osl=en&deviceid=16027&devlib=0&typecnt=0&vercnt=2&catid=-1&impid=-1&formatcnt=0&libid=17&typeid=-1&dateid=-1&formatid=-1&source=-1&fileid=379428

*) trying different versions of the webcam driver and the nefsis software I found the following behaviour:

Nefsis_build____Webcam driver___________Problem
=======================================================================
340_____________vanilla_________________none
340_____________1.02.02.0603____________Nefsis client says "old_driver"
340_____________1.08.01.0129____________BSOD

331_____________1.02.02.0603____________none
331_____________1.08.01.0129____________BSOD

325_____________vanilla_________________none
325_____________1.02.02.0603____________none
325_____________1.08.01.0129____________none

So it is quite clear to me that some change between Nefsis build 325 and 331 causes this BSOD issue with the latest webcam driver!

Is there anything I can do to help you identify the problem in detail (some kind of debug log)?

For work I'll stay with build 325 in the meantime.

Kind regards, Bernhard.
