Lenovo ThinkBook 14x ILL design: aluminum chassis, starting at just 990g

The Lenovo ThinkBook 14x ILL features an aluminum top cover and base, sandblasted and anodized for a smooth finish that resists fingerprints. The configuration available at Hung Phat Laptop comes in Luna Grey with a dual-tone finish on the lid, creating a clean, professional aesthetic.

Starting at just 990g and measuring 312 x 217 x 12.9-15.6 mm, it ranks among the lightest 14-inch business laptops on the market. It also meets MIL-STD-810H military durability standards, so you can slip it into a handbag or compact backpack for all-day meetings and business trips without feeling weighed down. If you are looking for a thin and light Lenovo laptop for work, the ThinkBook 14x is well worth considering.

Lenovo ThinkBook 14x ILL display: 14-inch WUXGA 120Hz, 100% sRGB

The Lenovo ThinkBook 14x ILL (2026) features a 14-inch WUXGA (1920 x 1200) IPS display panel with a 16:10 aspect ratio, a 120Hz refresh rate, 400 nits of brightness, and 100% sRGB color coverage. The taller 16:10 ratio displays more document lines and spreadsheet rows than a standard 16:9 screen of the same size.

The 120Hz refresh rate makes scrolling pages and dragging windows noticeably smoother than on the 60Hz panels typically found on office laptops. An anti-glare coating, 400 nits of brightness, and TÜV Rheinland Low Blue Light certification make working near windows easier while easing eye strain during long working sessions. The display is non-touch, making it ideal for professionals who work primarily with a keyboard and touchpad.

The available configuration is powered by the Intel Core Ultra 5 226V processor with 8 cores and 8 threads (4 performance cores and 4 efficient cores), a boost clock up to 4.5 GHz, and 8MB of cache. The processor integrates an Intel AI Boost NPU delivering 40 TOPS, meeting Copilot+ PC requirements to run on-device AI features like Windows Studio Effects, Live Captions, and smart search.

In daily use, the Core Ultra 5 226V capably handles standard office tasks, accounting software, video calls, light photo editing, and heavy browser multitasking. Lunar Lake stands out for its consistent performance on battery and low power draw, keeping the laptop cooler and delivering noticeably longer battery life than previous-generation office chips.

The integrated Intel Arc 130V graphics scores around 3,388 points in 3DMark Time Spy Graphics according to Notebookcheck - nearly double the 4-core Intel graphics on Core Ultra U-series chips - providing ample power for light Full HD video editing and casual eSports gaming at low settings. The 16GB of LPDDR5X-8533 RAM is integrated on-package and non-upgradeable, which is plenty for most business tasks. Storage is handled by a 512GB PCIe 4.0 SSD in an M.2 2242 form factor, with an extra M.2 2280 PCIe 4.0 slot available to install a second drive whenever you need more space.
