Greetings,

I transmit to you, across the time and space that separate us, this entreaty for help with my Dell device.

The hardware involved is a Dell Latitude 7212 Rugged Extreme Tablet and a Dell part number 04jwh4 docking station.

While at home, I usually leave the tablet in the aforementioned dock. Sometimes, while the tablet is on, I desire to use the tablet in an undocked state. Prior to the Windows 10 20H2 update, I was able to gently remove the tablet from the dock, and it would continue to work.

However, after the Windows 10 20H2 update, when I undock the running tablet, it works for about 15 seconds then hangs. The screen remains on, but the tablet is completely unresponsive. The only way to recover is to hold the power button down to perform an ungraceful shutdown, then power the device on again.

I attempted the 20H2 update a few weeks ago, and the same thing happened. After restoring the device to a previous point in time, the problem cleared. I figured I would give Dell and Microsoft a few weeks to sort the problem out, however, this afternoon I ran the update, and the problem persists.

I am diligent about keeping the tablet's drivers and firmware up-to-date. I have both Dell SupportAssist and Intel's Driver and Support Assistant installed. Both utilities report that there are no newer drivers for my device.

In the spirit of sharing information, I am attaching the following documentation:

- A screen shot from Belarc Advisor which contains detailed information about the system, including the service tag,

- A screen shot from Microsoft's System Information screen,

- A screen shot from Dell's support site attesting to the machine's warranty status,

- A screen shot from Dell's SupportAssist utility. Note that, I have recently run the various support tasks, and that no new drivers or firmware updates are available. Note also, that, as of this writing, I have a service contract in effect. Further note that I have enabled the option for Support Assist to transmit telemetry to Dell for troubleshooting purposes.

Does the dock have its own firmware? I tried looking for the dock firmware but my search was fruitless.

Perhaps, as a gesture of goodwill, Dell could lend me a Dell Universal Dock D-6000 to use while we work on this issue.

I appreciate your assistance.
