([manualslib.com](https://www.manualslib.com/manual/2600071/Lenovo-Thinkpad-X1-Carbon-Gen-10.html?utm_source=openai))  \n- In the \u201cRemoving or Replacing a FRU\u201d section, the **1080 Audio Board** is listed among the major subassemblies (\u201cFRUs/CRUs\u201d) that can be removed or replaced without replacing the system board. ([manualslib.com](https://www.manualslib.com/manual/3103848/Lenovo-X1-Carbon-Gen-10.html?utm_source=openai))  \n- The module involves the connector/cable that links it to the mainboard; Lenovo\u2019s manual shows there is an **audio connector** as one of the listed internal connectors. ([manualslib.com](https://www.manualslib.com/manual/2600071/Lenovo-Thinkpad-X1-Carbon-Gen-10.html?utm_source=openai))  \n\nFurthermore, there are genuine replacement FRU parts available for the audio jack / audio board for Gen 10. Examples include:\n\n- Part number **5M21D97366**, which is listed as compatible with X1 Carbon 9th, 10th, and 11th Gen models. This suggests the jack is not merged into the motherboard but is a discrete part that can be disassembled and swapped. ([notebookparts.com](https://notebookparts.com/products/new-genuine-lenovo-x1-carbon-9th-gen-10th-gen-11th-gen-5m21d97366?utm_source=openai))  \n- Replacement \u201cUSB & Audio Port Board\u201d modules for Gen-10 are sold (for example, from GotLaptopParts) as separate components. ([gotlaptopparts.com](https://www.gotlaptopparts.com/products/lenovo-thinkpad-x1-carbon-gen-10-14-genuine-laptop-usb-audio-port-board?utm_source=openai))  \n\n---\n\n## What It Means: Jack vs. Motherboard Wiring\n\nPutting the above together:\n\n- The **3.5 mm headphone/microphone combo jack** isn\u2019t simply soldered permanently onto the mainboards\u2019s audio codec chip\u2014it is part of a replaceable sub-board (\u201cAudio board\u201d FRU), connected to the system board via a cable and connector. ([manualslib.com](https://www.manualslib.com/manual/2600071/Lenovo-Thinkpad-X1-Carbon-Gen-10.html?utm_source=openai))  \n- The audio connector is accessible via disassembly: you remove the base cover, unplug battery, etc., then remove screws holding the Audio board, disconnect its connector. The jack lives on that board. ([manualslib.com](https://www.manualslib.com/manual/2600071/Lenovo-Thinkpad-X1-Carbon-Gen-10.html?utm_source=openai))  \n\n---\n\n## Conclusion\n\nSo, to answer your question: **on the ThinkPad X1 Carbon Gen 10, the headphone jack is not hard-wired permanently** to the main motherboard as a monolithic soldered pad. It is part of a separate, replaceable audio board/subassembly. If the jack fails, that audio board module (jack + connector + small board) can be replaced without replacing the whole motherboard.\n\nIf you want, I can walk you through how to identify the exact FRU number for your unit or give you instructions to replace it safely."
