I'm using a thunderbolt eGPU and getting it to work was like pulling teeth.  Make sure you have the latest firmware/drivers, uninstall everything with it all unplugged (but leave in a power charger), and make sure you flash to latest firmware.  I had it working fine for weeks, then today it decided to disable everything and although it powered up the external GPU it would say its disabled in the thunderbolt software centre, stating i needed a new firmware.


I was on latest but it didn't matter, After some digging, I removed the thunderbolt software, reinstalled everything, reflashed the firmware, powered everything off after rebooting a few times to complete the installs then finally from a cold boot (i.e. completely powered down not restart), with my thunderbolt device plugged in, powered on.


This then worked again.


There's a very serious bug with thunderbolt firmware (you should be getting warnings if you go to the site/use vantage), so if you haven't flashed to latest it could be dead and needs to go back to lenovo to have it replaced.
