E7470 BSOD when removed from Docking station

Hi,

Pretty much what the title says.....  When I remove the Latitude E7470 from

the docking station (E-Port Plus II Model PRO2X)

it Blue Screens with a APC_INDEX_MISMATCH.

Can anyone help with what I pasted.

Thanks

RE: E7470 BSOD when removed from Docking station

Have 3 7470s getting BSOD since updating to BIOS 1.17.5. The other almost 20 on older version are fine. 1 crashes on every undock. The other 2 are crashing while docked.

RE: E7470 BSOD when removed from Docking station

I too have a Dell E7470 running windows 7, I got the same BSOD, 3 times ,  (Twice pluging an HDMI monitor in, and other just starting an application), APC_INDEX_MISMATCH (1), all pointing to process:  audiodg.exe when I upgraded to Bios 1.17.5 also.

I am testing down grading the bios to 1.16.4 to see if the these go away.  I am not seeing this on my other E7470 but they were not on this version of bios of 1.17.5.

Here is a sample of my debug when plugging an HDMI monitor.

RE: E7470 BSOD when removed from Docking station

I too have bluescreens  with very similar dump files on Dell E7470 bios version 1.17.5.

(twice when plugging an HDMI external display and once just opening an application)

My other E7470 are not at same bios have not seen this issue either.

I have just downgraded my bios to 1.16.4 and see if the problem goes away.

Thanks -TC

RE: E7470 BSOD when removed from Docking station

I too have the same debug analysis pointing to audiodg.exe but when plugging in HDMI external monitor and once just opening an application.  I am testing a downgraded bios version 1.16.4.

I was at 1.17.5 running a Dell E7470 with Windows 7.

RE: E7470 BSOD when removed from Docking station

I am also receiving the same error, but slightly different. This is confirmed on 3 different E7470s while either on a dock or removed from a docking station.

RE: E7470 BSOD when removed from Docking station

Hi,

we have the same issue with 2 of our 7470s. The laptops crashed frequently when docked, but also in meeting rooms without docking. We got rid of the problem on one laptop by reinstalling it completely. On the other we still have the same issue. Drivers and BIOS have been updated with DELL command Update. We have a support case open, but so far we were only asked to try previous version of the audio driver. Unfortunately we are still getting the BSODs and the user is getting annoyed.

RE: E7470 BSOD when removed from Docking station

The folks that tried the BIOS version 1.16.4,1, how has that worked out for you?

Unfortunately, rolling back the BIOS to 1.16.4.1 on an affected machine did not stop the blue screens.

Also... Speaking of the BIOS... In the details for BIOS 1.17.5, what does "Fixed system black screen issue if exit BIOS setup after attached external display device on docking" even mean?!? Does the issue occur if a user attaches/connects an external monitor while in the BIOS? Does the issue occur if the user has an external monitor attached prior to entering the BIOS?

RE: E7470 BSOD when removed from Docking station

I have used Dell command update to update all drivers on the affected 7470s.

After some more bluescreens I removed the Realtek audio driver and the Intel video (including display audio) and installed previous versions:

Realtek-High-Definition-Audio-Driver_331N1_WIN_6.0.1.6122_A08

Intel-HD-Graphics-500-P500-600-P600-series-Driver_C2N7T_WIN_21.20.16.4627_A02

There have been no BSODs for 2 days now. I am keeping my fingers crossed it keeps that way and this is finally solved!
