So I have been troubleshooting this for the past week, I am using the ASUS Zenbook S 14, which has an Ultra 7 268V processor and thunderbolt 4.
But if I plug in any real thunderbolt device like a eGPU dock, Intel PCI Express upstream port won't start and laptop will loses trackpad, wifi, audio. After searching the internet, It looks like this issues affect other laptop with lunar lake.
Is there any on can help ?
