In several cases, with multiple generations of the E15 we saw this happen.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Running the updater will give errors, mostly that it can not read the current version of the various hardware revisions, and it will eventually fail.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Other laptops will work with the dock, both Windows and macOS alike. The dock is usable for USB, ethernet, and audio, but video will be non-responsive and not shown as available.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Resolution:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Firmware downgrade!<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Using this recent Reddit thread I was able to get the 3.0.80 firmware from Lenovo.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Using a Dell laptop with USB-C I was able to successfully install the previous firmware version and downgrade to 3.0.80. All functions return and the dock is completely usable.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">I&#8217;ve done this without issue on 4 of the 40AY USB-C docks and all devices which were not previously working are now operating properly.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><em>Update &#8211; 01\/08\/24<\/em><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Lenovo has since released the 3.0.92 firmware update for these docks and I can confirm that it avoids this issue. One dock that had been downgraded was successfully upgraded from .80 to .92 and all functionality worked. Another was a recent .91 firmware install that I was unaware of, a successful downgrade, and then an upgrade to .92.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Reddit thread:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.reddit.com\/r\/sysadmin\/comments\">https:\/\/www.reddit.com\/r\/sysadmin\/comments<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>A bit of a firmware downgrade story: Lenovo Thinkpad Universal USB-C dock firmware issue with AMD-based E-series laptops.
