System76 has refreshed its thin-and-light take on Linux laptops, the company announced Tuesday, as spotted by Tom’s Hardware. The revamped 14-inch Lemur Pro, like its predecessors, prioritizes a longer battery life, with the latest model claiming up to 14 hours of use.

[Update July 8, 2022, 9:28 a.m. ET: A spokesperson for System76 told Ars Technica that the battery life claim was determined after testing under four conditions:
- Editing text in Vim with the screen at 50% brightness
- Editing text in Vim with the screen at 100% brightness
- Streaming a video on YouTube in Firefox with the screen at 50% brightness
- Streaming a video on YouTube in Firefox with the screen at 100% brightness]
The Lemur Pro has a proven reputation for solid battery life. In our Lemur Pro review in 2020, when the machine was offered with an Intel Core i7-10510U, it lasted at least one hour longer than any other laptop we reviewed around that time when playing BBC’s “10 Hours of Relaxing Oceanscapes” at 1080p resolution and max brightness.

It was clear that System76 had fine-tuned the machine more for longevity between charges than productivity performance.

The 2022 Lemur Pro is configurable with up to an i7-1255U, part of Intel’s U-series aimed at machines more concerned about power efficiency. The i7-1255U specifically has two high-performance P-cores (1.7–4.7 GHz), eight efficient E-cores (1.2–3.5 GHz), 12 threads, and 12MB of cache. For a quick comparison, System76’s larger (15- or 17-inch) Gazelle laptop, which includes an Nvidia RTX 3060 laptop graphics card, has an i7-1200H with six P-cores (2.3-4.7 GHz), eight E-cores (1.7-3.5 GHz), 20 threads, and 24MB of cache.
But the Lemur Pro is more about battery longevity and portability, as you can tell from its 2.54-lb weight and 0.65-inch thickness.

It’s also configurable with up to 40GB of dual-channel DDR4-3200 RAM (8GB + 32GB) and 4TB of storage available over two M.2 slots (up to one PCIe 4.0 and one PCIe 3.0).
Other specs include a 1920 x 1080 display, a 1080p webcam, two USB-A ports, one Thunderbolt 4 port, and a Micro SD card reader, plus the option to run Ubuntu 22.04 LTS or Pop!_OS 22.04 LTS.

The laptop’s firmware uses the Coreboot open source firmware platform, and its embedded controller firmware is open source, too.
System76’s Lemur Pro starts at $1,150.
