Issue – Lenovo UCSI USB Type-C firmware upgrade failed. USB Type-C ports no longer work and I have a yellow exclamation mark on the UCSI USB Connector Manager in Device Manager. And that means… no more power to the battery. Which is about when you realize, this is a tech issue with a timer. You sir have 3 hours and 5 minutes to prevent your brand new shiny bad ass laptop from becoming a shiny new expensive brick packed in a Fed-Ex box on it’s way to a Lenovo repair facility somewhere in Texas. Cause you know, USB has always been so reliable on the WinTel platform why wouldn’t you make it the power source!?
How did we end up here? Because the satellite launch capable Lenovo Yoga 920 (4k, 16gb ram, 1tb disk, 8th gen i7-8550U @ 1.8ghz/8mb) when running Windows 10 Fall Creators Update v1709 or later isn’t capable of USB-C output to any HDMI display. No external display on a TV or computer monitor unless you’ve fully powered off the laptop and performed a cold boot with all cables connected and even then it’s flaky. Have I mentioned how well USB works with Windows? So yeah, Lenovo issued a firmware update that fixes the issue which is great, it just may occasionally go south.
Solution! – Disconnect all cables from the laptop, then press and hold the power button for 8 seconds. That’s it! Worked for me! This forces a PD System reset which almost instantly started delivering power.
The solution was found in line 3.b of the Lenovo Yoga920 PD FW V55 Update readme:
1 2 3 4 5 6 7 | Note :before update PD FW, please makesure 1. Battery Remaining capacity more than 60% 2. Type C adapter is connecting to system. 3. When udate fail, a. please unplug Type C adapter and all Type C device , b. Press power button more than "8 "second to force system PD reset. c. Run the update process again.. |

Hi,
well, google found this page and the solution works like a charm. :)
Thanks for the post! The update is failing for my Lenovo yoga 920 laptop and I can’t get make the Type C ports work again. I can’t charge my laptop.
I tried holding the power button for more then 8 seconds, but it doesn’t help. My laptop shuts down after 5 seconds. I turn it back on, still won’t charge. I tried few times.
I posted a question on Lenovo forums and hoping for a quick solution. My battery is down to 75%.
