    ThinkPad Thunderbolt 3 failure:What's happening,why it's happening,and how to fix

    The thread title is from a recent news article (and a follow up) on notebookcheck about Thunderbolt 3 failures.
    Quote:
    Nearly 40 ThinkPad models have a problem - the Thunderbolt 3 ports in them randomly stop working. Lenovo has pushed out a fix to users, but what does it do? Does it actually solve the problem? If it doesn't, are the devices even repairable, and will Lenovo repair your device for free?

    Lenovo notes these symptoms on their knowledge base page:
    USB-C port not working
    Intel Thunderbolt controller not visible in the OS/Device Manager
    USB-C or Thunderbolt docking stations not visible or having connectivity problems
    HDMI output not available
    System battery not charging with a USB-C power adapter connected to the USB-C port
    Intel Thunderbolt pop-up error message
    Intel Thunderbolt safe mode error message
    BIOS Thunderbolt communication error or hang during POST

    Re: ThinkPad Thunderbolt 3 failure:What's happening,why it's happening,and how to fix

    Would this cause a boot failure by chance?
    Things I've fixed: anything from semis to crappy Chinese $2 radios, and now an IoT Dildo....

    "Dude, this is Wyoming, i hopped on and sent 'er. No fucking around." -- Me

    Excuse me while i do something dangerous


    You must have a sad, sad boring life if you hate on people harmlessly enjoying life with an animal costume.

    Sometimes you need to break shit to fix it.... Thats why my lawnmower doesn't have a deadman switch or engine brake anymore

    Follow the white rabbit.
