Lenovo IdeaPad Slim 3i laptop 15.6" i5-1335U 16GB LPDDR5 1TB NVMe Windows 11 Pro Arctic Grey

15.6-inch TN display laptop

The Lenovo IdeaPad Slim 3i uses a 15.6-inch TN panel with a 1920 x 1080 resolution and a 60Hz refresh rate. It runs Windows 11 Pro on a 13th Gen Intel Core i5-1335U processor with 10 cores and 12 threads. Integrated Intel Iris Xe graphics handle the visual output. This configuration suits office workers and students who need a reliable daily driver.

Sustained workload behaviour

The i5-1335U operates at a 1.30GHz base frequency and can reach 4.6GHz turbo across two performance cores. Under continuous load the 65W power supply and 47 WHr battery limit how long peak speeds hold. The 16GB LPDDR5 memory is soldered and cannot be expanded later. Buyers who need more storage or memory bandwidth should look elsewhere.

Installation and common issues

The laptop arrives with the operating system and drivers pre-installed so first boot is straightforward. A Dockztorm wireless mouse is included in the package. The chassis measures 9.4 x 14.15 x .8 inches and weighs 3.5lb. Ports include HDMI, USB 3.2 Type-C, an SD card reader and a combo audio jack. Some users find the TN viewing angles restrictive compared to IPS alternatives.
