ThinkPad T15 Gen 2i business laptop

The Lenovo ThinkPad T15 Gen 2i is a 15.6-inch business laptop running Windows 11 Pro. It is built for office workers and mobile professionals who need a reliable daily driver. The black chassis houses a quad-core Intel Core i5-1145G7 processor clocked at 2.6GHz with 8MB L3 cache. It ships with 16GB of DDR4 memory and a 512GB PCIe NVMe solid-state drive.

Integrated graphics and display

The single specification that decides suitability is the integrated graphics paired with a 1920 x 1080 IPS panel. This combination handles document work, web apps and video playback but cannot accelerate 3D rendering, CAD or modern gaming workloads. Buyers who need discrete GPU performance for creative or engineering tasks should look elsewhere.

Thermal behaviour under load

Under sustained load the quad-core processor will hit its thermal limits and reduce clock speeds to maintain safe temperatures. The 16GB DDR4 memory and 512GB NVMe drive remain responsive, yet the integrated graphics share system memory and generate additional heat during prolonged video encoding or heavy multitasking. Expect performance to settle below the 2.6GHz base frequency during extended sessions.
