The lightest depends on what you count\u2014size, functionality, whether keyboard/docks are included, etc.\u2014so I'll give you top contenders and what makes each unique.\n\n---\n\n### \ud83e\udd47 Top Lightest Full Laptops (with Keyboards)\n\n| Laptop Model | Weight | Screen Size / Details | Why It\u2019s Notable |\n|--------------|--------|-------------------------|------------------|\n| **Acer Swift Blade 14** | ~1.76 lb (\u2248 799 g) ([tomshardware.com](https://www.tomshardware.com/laptops/acers-swift-blade-14-weighs-just-1-76-pounds-and-uses-wildcat-lake-company-introduces-new-sub-brand-ahead-of-ifa-tradeshow?utm_source=openai)) | 14-inch, thin design, aluminum-magnesium + carbon fiber body ([tomshardware.com](https://www.tomshardware.com/laptops/acers-swift-blade-14-weighs-just-1-76-pounds-and-uses-wildcat-lake-company-introduces-new-sub-brand-ahead-of-ifa-tradeshow?utm_source=openai)) | Currently described as \"the world\u2019s lightest laptop to be launched globally\" based on its design and weight. ([techradar.com](https://www.techradar.com/computing/windows-laptops/the-new-acer-swift-blade-14-is-the-worlds-lightest-laptop-to-be-launched-globally?utm_source=openai)) |\n| **Fujitsu FMV Note U (WU1-K1)** | ~1.87 lb (\u2248 848 g) ([techspot.com](https://www.techspot.com/news/106456-187-pounds-fujitsu-fmv-note-u-world-lightest.html?utm_source=openai)) | 14\u2033 non-glare LCD, made for business with good CPU specs ([techspot.com](https://www.techspot.com/news/106456-187-pounds-fujitsu-fmv-note-u-world-lightest.html?utm_source=openai)) | Held the title of the lightest laptop on the market for its class until others like the Blade 14 appeared. ([techspot.com](https://www.techspot.com/news/106456-187-pounds-fujitsu-fmv-note-u-world-lightest.html?utm_source=openai)) |\n| **Dynabook RA73/VY** | ~849 g (~1.87 lb) in base (non-touch) version ([techradar.com](https://www.techradar.com/pro/dynabook-ra73-vy-the-lightest-amd-laptop-ever-launched-has-gone-on-sale-in-japan-and-i-secretly-hope-it-will-be-available-worldwide?utm_source=openai)) | 13.3\u2033 with AMD CPU; slightly heavier if touch display added ([techradar.com](https://www.techradar.com/pro/dynabook-ra73-vy-the-lightest-amd-laptop-ever-launched-has-gone-on-sale-in-japan-and-i-secretly-hope-it-will-be-available-worldwide?utm_source=openai)) | Holds record as the lightest **AMD notebook** in some regions. ([techradar.com](https://www.techradar.com/pro/dynabook-ra73-vy-the-lightest-amd-laptop-ever-launched-has-gone-on-sale-in-japan-and-i-secretly-hope-it-will-be-available-worldwide?utm_source=openai)) |\n\n---\n\n### \u26a0\ufe0f Other Ultralight Options (Special Categories)\n\n- **Very Small or Tablet-style Devices:** There are ultra-portable mini-laptops or tablets with keyboard docks weighing *far* less than 1 kg. For example, the **GPD Win 4** (handheld, ~0.6 kg) or **Fujitsu FMV Zero** (business-oriented, ~0.64 kg). These are extremely light but are stripped down in size and might not qualify as \u201cfull laptops.\u201d ([ultrabookreview.com](https://www.ultrabookreview.com/4219-the-lightest-ultrabooks/?utm_source=openai))\n- **Companies with regional-only releases** have produced very light laptops (e.g., Fujitsu\u2019s UH-X series), but availability is limited. ([tech.yahoo.com](https://tech.yahoo.com/computing/articles/lenovo-quietly-launched-world-lightest-030032122.html?utm_source=openai))\n\n---\n\n### \ud83c\udfaf Which One\u2019s *the Lightest*?\n\n- If you want a full-sized 14-inch laptop with keyboard and modern ports, the **Acer Swift Blade 14** is arguably the lightest globally launched option as of now. ([techradar.com](https://www.techradar.com/computing/windows-laptops/the-new-acer-swift-blade-14-is-the-worlds-lightest-laptop-to-be-launched-globally?utm_source=openai))  \n- If you allow smaller devices or very minimalist form factors, there are even lighter ones\u2014but they often come with trade-offs (screen size, port availability, performance, etc.).  \n\n---\n\nIf you tell me what \"lightest\" means to you\u2014like whether screen size matters (14-inch vs 13-inch), price range, region of availability\u2014I can narrow down the best pick for *your* use case."
