However, I located **community-sourced data** (via Linux hardware repositories) that give useful estimates, with clear references.\n\nHere\u2019s what I found:\n\n---\n\n### Community-Sourced Dates (from Linux Hardware Data)\n\nFrom linux-hardware.org:\n\n- BIOS **1.51** for ThinkPad X1 Carbon Gen 10 (code N3AET86W) was available by **June 3, 2025**. ([linux-hardware.org](https://linux-hardware.org/?probe=55c36b63ae&upgrade=&utm_source=openai))  \n- BIOS **1.52** soon followed on **August 6, 2025**. ([linux-hardware.org](https://linux-hardware.org/?probe=55c36b63ae&upgrade=&utm_source=openai))  \n\nThese entries imply:\n- Version 1.51 \u2192 ~ **June 3, 2025**\n- Version 1.52 \u2192 ~ **August 6, 2025**\n\n---\n\n### What is Still Unclear\n\n- **Version 1.53**: I did *not* find a data point that reliably shows the release date of BIOS 1.53 for Gen 10.\n- **Official Lenovo sources** (support site, PSU/PSREF, firmware listings) do *not* clearly list the release dates for 1.51 or 1.53 for this model.\n\n---\n\n### Conclusion\n\n- BIOS **1.51** was released **around June 3, 2025** for ThinkPad X1 Carbon Gen 10 (per linux-hardware.org) ([linux-hardware.org](https://linux-hardware.org/?probe=55c36b63ae&upgrade=&utm_source=openai))  \n- **No reliable date** was found for BIOS **1.53** for the same model.\n\nIf you like, I can try digging through archived Lenovo pages (using Wayback Machine) or contacting firmware version metadata to try to nail down the 1.53 date, but it may still remain undocumented. Do you want me to attempt that?"
