Update, 2 June 2023:
I’m pleased to report that I was able to get the 3.06 Beta BIOS upgrade completed by disabling the Secure Boot setting in the BIOS and then using the EFI method with a USB Flash drive. I’ll update this post with any additional issues I discover.
=======================
Original Post (1 June 2023):
I finally gave up waiting for the 3.06 to be out of Beta and ran the update on my 12Gen, which was still running the BIOS and firmware it shipped with back in Sep 2022.
I’m pretty unhappy with the way this went - if anyone has suggestions I’m all ears. Thanks in advance for any advice. The gory details:
Result of upgrade: Can no longer dock with right side ports
Right side USB-C/TB ports only recognize power delivery from the docking station - no other connectivity is recognized. When docking station is connected to either left side port, using either of the two USB-C modules I have, everything appears OK (extremely minimal testing so far). The USB-A port connected on the right side appears to be running normally - able to run 3.0 devices.
Upgrade method used:
Windows MSI on Windows 11. There were a lot of reboots, and the last one’s green progress bar took several minutes to complete the last 1-2% - it was stuck in the same spot long enough that I was getting nervous that it was going to fail (it did not). nothing else was obviously noteworthy during the process. I did video most of it, if anyone is interested.
Attempts to remediate the right side docking issue:
-
Tried to run update via USB EFI, but it won’t run. Tried several times with power connected to both sides - same result.
] -
Re-ran the .MSI installer in Windows, a few times, with power connected on both sides. Same result each time - it says it needs to reboot to apply the update, but nothing appears to actually get installed or runs - it just looks like a normal reboot, and the docking situation is unchanged.
Conditions under which upgrade was performed:
Hardware: 12 Gen DIY Received Sep 2022 Batch 3
BIOS version 3.04 (BIOS that shipped with this system)
Modules in laptop:
Rear Right: USB-C, connected to Dell TB3 Docking Station (TB16)
Front Right: USB-A, connected to Mouse
Rear Left: USB-C, not connected to anything
Front Left: HDMI, not connected to anything
The docking station is a Dell TB16 that has been working quite well for the last 5-6 months. Only issues prior to BIOS/Firmware upgrade were with reboots. If the dock was connected at reboot time, the power delivery would stop - disconnecting and reconnecting it would solve that problem reliably.
