Dawson Visual issue
This document exists to go over the current information we have for troubleshooting the Dawson video flickering issue. We are looking to gather as much info as possible regarding this. Whenever a support case is worked where we see this issue, encourage the customer to send an Intel SSU report.
Intel SSU tool (System Support Utility):
Drivers: Always start with Drivers. I’ve been encouraging people to use the Driver assistant (DSA) - https://www.intel.com/content/www/us/en/support/intel-driver-support-assistant.html
Monitor: There are two things of note here.
This one has a bit of contention. I believe that when a driver is released. We will want our hardware on this version. At this time simply doing this step doesn’t resolve the problem.

*Updated to F/W Version: Bobcat App: MC2800 v1.71 (cut2.2)

My next step was to dig into Regedit and attempt to resolve the problem through there. I did notice that there was an issue with the Intel Management Engine that was consistently reporting as an error when looking up the HDMI visual packet loss. Booted into Safemode to delete Intel Management Engine without issue, then removed all trace through Registry and File Explorer
Regedit file remnants found in:
(HKEY_CURRENT_USER\Software\ Intel Management Engine Components)
(HKEY_LOCAL_MACHINE\Software Intel Management Engine Components)
File Explorer remnants found in:
(C:\Document and Settings\All Users\Application Data\)
(C:\Documents and Settings\%USER%\Application Data\)
Then Installed Intel Management Engine 1909.12.0.1236 Via Driver assistant tool listed above.
