- Dual SO-DIMM slots supporting up to 128 GB RAM alongside dual SSD slots
- Revised all-aluminum chassis reducing thickness and carry weight
- Optional 120 Hz WQHD display delivering fluid motion and crisp text
- Modern connectivity including Thunderbolt 4 and Wi-Fi 7
- Modest graphical compute throughput from entry-level 4-core integrated GPU
- Base configurations may ship with single-channel memory
Overview
Transitioning to a revised all-aluminum chassis marks a welcome physical evolution for Lenovo’s entry enterprise lineup, trimming both thickness and overall carry weight without sacrificing keyboard stability. The enclosure retains the brand’s signature tactile typing deck, pairing deep key travel with a rigid palm rest that resists localized flex during brisk daily documentation.
Under the hood, the Intel Core Ultra 5 225U Arrow Lake processor focuses on balanced office efficiency, maintaining low thermal output and hushed fan acoustics that help preserve long battery runtimes across extended workdays. Visual tasks benefit substantially from the optional 120 Hz WQHD display, which brings fluid motion tracking and sharp text rendering to daily spreadsheets and multi-window multitasking. While the 4-core integrated graphics engine handles general productivity and multimedia playback with ease, graphics-heavy workloads remain bounded by its modest execution core count.
Where this machine truly diverges from modern laptop trends is internal serviceability. Rather than soldering memory to the mainboard, the architecture provides two full SO-DIMM slots supporting up to 128 GB of RAM alongside two dedicated SSD slots. Combined with high-speed Thunderbolt 4 connectivity and Wi-Fi 7 wireless support, the system offers an exceptionally clear path for long-term component upgrades and straightforward fleet maintenance, though buyers should verify dual-channel memory configurations to unlock full system bandwidth.
