Get same false positive in Dell Diagnostics for LCD cable error 2000-0415 when I updated the Bios to A3. The error is no longer there (all green check marks) when I rolled the Bios back to A2. Dell needs to fix this A3 bios bug and update the bios to A4. I see the same problem with other Bios (A7) in the Latitude E65XX series.
I have same problem.
I just purchased a dell E5520 and I get the same error in diags. I wonder if it is related to whether or not you have the backlite option of which I do not have.
do you have problems with the webcam ?
same issue here and the downgrading to a02 fixed it at least for now. Dell wanted to replace mono and screen... um... yeah, maybe just clean up the bios first.
Also got the same Errcode as i updated my bios... to version A08 on my E5420
ErrCode 2000-0415 Check LCD Cable
Found no solution for the moment.
Impact - hard to boot sometimes : no boot device founded !!!
Same issue on A09 BIOS. System seems to work fine.
