I've found out that for me it only locks up when the CPU goes into Turbo Boost while using the camera. Since I've turned off Turbo Boost in the BIOS setup it never happened to me again so far. Can you please try the same and share your results? I'm curious if this is a general Camera+TurboBoost issue or whether it's just something special about my setup...
Hi there! Has anybody ran into this issue before? We've deployed about 5 of these i7, 16GB, Latitude 9420 models to eupper level employees, and they're all coming back with the same concerns. Whenever they're in a Teams or Zoom call for more than 10 minutes roughly, the laptop itself will freeze completely. No audio cues, no mouse movement, and the screen will be frozen on whatever the last "image" was on the screen. Laptops plugged into a D6000 (and D6000s) docking station behave the same way, with all monitors freezing. We've attempted uninstalling all Camera Drivers, as well as installing the 4 recommended Camera drivers from the Support Page with no change in behavior (MCU Driver for Intel Visual Sensing, Intel Visual Sensing Driver, Intel Integrated Sensor Sensor Solution, and the Intel 2D Imaging Driver). When the laptop hangs in place, it does not BSoD at all either, but just freezes entirely. Event viewer simply has a message that states, " The description for Event ID 1 from source camera cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer. If the event originated on another computer, the display information had to be saved with the event. The following information was included with the event: ov01a1s The locale specific resource for the desired message is not present"   Any help would be much appreciated! ST/Serial:
