16-inch 2-in-1 with Core Ultra 7

The Lenovo IdeaPad 5i 83KS001MUS is a 16.0-inch convertible laptop built around an Intel Core Ultra 7 255U processor. It ships with 16GB of LPDDR5x memory at 6400 and a 512GB NVMe SSD. The touch-enabled IPS panel delivers a 1920 x 1200 WUXGA resolution. Integrated Intel Graphics share system memory for everyday visual tasks.

Home users wanting touch flexibility

This configuration suits people who want a thin-and-light 2-in-1 for browsing, streaming and office work with pen or finger input. Buyers who need discrete graphics for gaming or heavy rendering should look elsewhere. Anyone requiring more than 16GB of RAM or multiple terabytes of storage will need a different model. The single 512GB drive also limits local media libraries.

Check memory and port needs first

The 16GB LPDDR5x is soldered and cannot be upgraded after purchase. Verify that 512GB NVMe capacity meets your workload before ordering. Connectivity includes two USB 3.2 Gen 1 Type-A ports, two USB 3.2 Gen 2 Type-C ports, one HDMI output and a combo audio jack. Confirm these interfaces match your peripherals and external displays.
