Dell Precision 7550 and 7750 System BIOS - 1.24.0 Breaks Docking Station USB C
After months of WD19S docking station not working due to a bios issue, Dell fixed it.
A new Forced windows update bios 1.24.0 now breaks USB C again.
The Docking station will only power through 1 USB not both at the same time!!!
The Laptop powers down at it can't provide enough power.
Also my screens don't work either.
Why don't dell test before release.. there is no roll back with this BIOS either so probably have wait another 6 -12 months to use the Dock and all the accessories attached.

@DELL-Nathalia M
Thank you for the updates. It also does not work for me on a 7550. Still no display after plugging in a 180W adapter and then the dock using a 240W. One light on the dock USB-C connectors, whichever plugged in first. My only external display is 4k HDMI, only works plugged into the laptop directly still.
While in the office today I tried several docks and could only get a WD15 to even give me USB and network. An old Thunderbolt dock isn't even recognizing for charging any longer. It seems that thunderbolt is completely non-functional.

I was with Dell support for hours with the same issue. The engineering team is aware of the issue but they don't have a date for the new BIOS release to fix this issue.

FYI - Dell Engineering is aware of this issue and are currently working diligently on a solution. No ETA yet, but will keep you posted.
In the meantime we are recommending you also plug the AC adaptor that shipped with your system directly into your system to provide sufficient power to your system.

@DELL-Nathalia M The "diligent" solution would be to re-release the previous BIOS version as an interim incremental version "1.24.1" hotfix to allow people to get back to work while Dell Engineering figures out what went wrong ON THEIR TIME, NOT OURS!

@DELL- Nat M The 1.24.0 update broke my USB C so only one works at a time... My Help Desk worked with Dell Support, and they Next Day Air shipped a new docking station to solve the problem, but it doesn't. The problem is not the docking station, it the USB C ports in the laptop itself.

As many of you noticed the problem is not the WD19DC. Replacing the WD19DC with another WD19DC does not help at all. The USB Type-C ports in the laptop are a bit broken after BIOS update.
What can be done if you have several external displays is to start using Dell dock WD19TB. This is Thunderbolt version of the WD19 family. Thunderbolt cable has enough bandwidth to run several displays and network in the single cable.
You still must use the charger provided with the laptop using WD19TB. Dock has its own charger but it's not enough. Thunderbolt cable has the same power limit as single USB Type-C cable. That's why the WD19DC has two cables. Each cable is providing about 90W. Dell Precision 7X50 requires about 180W to run at full speed.
Your local IT department may help you. But if you are at home with single laptop, you must wait the next BIOS update.
WD19 dock has replaceable head. In theory you can convert WD19DC to WD19TB.

@DELL- Nat M Can you PLEASE ask Dell Engineering for an update on this? It's been a week with no resolutions when they could have simply rolled back the changes for now as an interim fix. Their update broke our systems and we need something from them to get them working again, either a rolled back update or an actual fix.

I was able to downgrade the BIOS to 1.22, but these issues still persist. Downgrading does not help.

Hi all,
Good News: A new BIOS will be released in mid-September to address the issue.
In the meantime, if you can't wait for the fix, please contact our agents by clicking "Get Help Now" for a temporary solution. This solution requires downgrading the BIOS and should only be attempted after the agent validates your system and receives approval to proceed with the downgrading instructions.
Feel free to ask if you have any more questions!

@DELL- Nat M It seems that it is not possible to downgrade, at least according to the representative that I chatted with. Tell engineering to re-release 1.23.1 as 1.24.1 as an interim fix.

@DELL- Nat M Please tell your engineering team that the community has determined that the give timeline for the fix of mid-September is unacceptable and that it will be delivered by 8/25. There is obviously no quality control as these firmwares constantly break Dell products, so it should be no trouble getting it out by 8/25. Or, you could take @ShanePitman advice and just re-release the last working firmware as the update (temporarily) so that all of us users of your low quality products are no longer hindered by Dell's incompetence.

Understood, thanks @ShanePitman. I'll send them the chat you just shared and ask for a new position. I'll let you know as soon as I get a reply.
