Lenovo ThinkBook 13s G4 ARB 21AS003FUS laptop AMD Ryzen 5 6600U 2.90 GHz 8 GB 256 GB SSD 13.3" 1920 x 1200

Lightweight 13.3" business laptop

The ThinkBook 13s G4 ARB is a 13.3" notebook built for mobile professionals who value a compact aluminium chassis. It runs Windows 10 Pro on an AMD Ryzen 5 6600U hexa-core processor clocked at 2.90 GHz. The 8 GB of onboard LPDDR5 memory and 256 GB M.2 PCIe SSD are fixed, so the specification suits users who need a ready-to-work device without internal upgrades.

Integrated graphics and fixed memory

The integrated GPU handles everyday productivity and video playback but is not intended for heavy 3D rendering or modern gaming workloads. System memory is soldered to the board, preventing any capacity increase after purchase. The single HDMI output supports one external display, limiting multi-monitor setups to a single additional screen.

Aluminium build with fingerprint power button

The grey aluminium body keeps weight low while resisting daily flex. A fingerprint reader integrated into the power button enables fast, secure sign-in without a separate sensor. The 13.3" WUXGA non-touch panel delivers a 1920 x 1200 workspace in a footprint that fits small bags and airline trays.
