ThinkPad T490 14" FHD Touchscreen Ultrabook

The Lenovo ThinkPad T490 is a 14.0-inch FHD touchscreen ultrabook built around an Intel Core i5-8250U quad-core processor with 6MB L2 cache. It ships with 16GB of DDR4 memory and a 1TB SSD running Windows 11 Pro. Integrated Intel UHD Graphics 620 handles the display output. This configuration suits professionals who need a portable, touch-enabled Windows machine for daily productivity and video calls.

Installation notes for memory and storage

The chassis uses standard DDR4 SO-DIMM slots and an M.2 slot that accepts SATA or NVME drives. Removing the bottom cover requires a small Phillips screwdriver and careful prying to avoid damaging the hidden clips near the hinge. The battery connector must be disconnected before any internal work. The single M.2 slot means total storage capacity is limited to the drive installed; there is no 2.5-inch bay for a second drive.

Capacity and headroom with 16GB RAM and 1TB SSD

Sixteen gigabytes of DDR4 memory provides comfortable headroom for typical office workloads, browser tabs, and light virtualisation. The 1TB solid-state drive offers ample space for applications, local files, and a large media library. Memory-intensive tasks such as heavy video editing, large dataset analysis, or running multiple virtual machines simultaneously will exceed the soldered-plus-socket memory ceiling of 32GB. Users needing more than 1TB of internal storage must replace the single M.2 drive rather than add a second one.
