Lenovo Ideapad 3i 15 laptop i5-1155G7 20GB 512GB FHD touchscreen Abyss Blue

Core performance

The Lenovo Ideapad 3i 15 is a 15.6 inch touchscreen laptop powered by an Intel Core i5 11th Gen processor with four cores running at 2.5 GHz up to 4.5 GHz. It includes 20GB of DDR4 memory and a 512GB PCIe SSD running Windows 11 Pro. This configuration suits students and office workers handling documents, web apps and light creative tasks.

Connectivity and expansion

The chassis provides one HDMI output, one USB-A 2.0 port, one USB-A 3.0 port and one USB-C 3.2 port for peripherals and external displays. Wireless connectivity covers Wi-Fi and Bluetooth, while a multi-format SD card reader adds removable-media access. The sealed design means internal storage and memory cannot be upgraded after purchase, so buyers needing more capacity should choose a different model.

Sustained operation

Integrated Intel Iris Xe graphics share system memory and handle everyday video playback and casual gaming without a discrete chip. The slim profile at 0.78 inches thick and 3.74 pounds weight limits thermal headroom, so extended heavy workloads will throttle clock speeds below the 4.5 GHz peak. Fan noise becomes audible under continuous load, and surface temperatures rise noticeably during long sessions.
