T470 - 20HE Thunderbolt firmware update

2019-12-04, 9:06 AM

Hi all

 

Been using the thunderbolt for few weeks, struggle to make it to work with multiple restarts and shutdown before it start to disapply on my monitor. Today non of that worked so I tried to uninstall the "Thunderbolt Software" and update the "Thunderbolt FW" but it's not working with multiple errors as below:

 

1- TB - SW version 17.4.80.41 installed/ NVM details are not showing.

 

2- TB - FW update error "No Active Thunderbolt(TM) Controller Found in the system

 

3- Detect 1810.exe ends with error

Capturing Current NVM Version.....

Capturing Current NVM Version failed!

Error: 0x20B SDK_NO_CONTROLLER -

 

4- TB is enabled in bios

 

5- Thunderbolt Controller is not showing under Manage devices, though show hidden is selected

 

6- Tried to reset while battery and charger off using the hole behind the laptop. Didn't work

 

7- Lenovo update showing no updates available, also windows and intel.

 

Now the TB port is completely inactive. 

 

Apprecieate any guidnce

I think you have tried everything possible.  Especially after your step #6, if it's still not working, I think the HW has failed.  Maybe try #6 again, and then #3 to see if you can query the firmware version.  Wish I had better news for you but I don't know what else to try.

Thank you 

 

I think somehow with some good luck and your old posts I managed to get it to work. I'm not sure which of the tens of steps I did today morning but looked it worked. Let me try to put all the steps I performed in logical order and I will share it back with you, hopefully it will help someone on day.
