Have a batch of 7390's and when they are docked and turned on they do not output the display to the attached screens. which means to enter bitlocker information you need to open the lid of the laptop up which is rather annoying. am i missing something. changed the bootloader to the mgrgui.efi one to enable the keyboard at this point bios is set to do a full post check. USB C is enabled etc any suggestions helpful these WD15 docks are a right pain had all sorts of other issues with docking and undocking and lan ports
Hi @SHimmer45 can you advise if you are running the latest BIOS on the system?
Can you try configuring the BIOS as per the following -
The necessary BIOS settings are similar for all 3 docking stations. Please refer to the individual notes in the following instructions.
Reboot your system and press the F2 multiple times at the Dell logo. In the BIOS, proceed as follows:
NOTE: For some systems, the following settings are all found under the section USB-Configuration.
NOTE: Please note that items 4 and 5 apply only to systems with Thunderbolt controllers. If this does not apply to your system, the options are greyed out or not available.
That will ensure you that have the latest updates on the system and ensure it's correctly configured for use general use. To address the Bitlocker query, I don't believe it's possible to have the Bitlocker prompt on the external screens pre Boot. I have a WD15 dock in front of me and I don't get video on my dual external displays until the system has logged into Windows. I believe that is a design limitation of USB-C technology.
