Lenovo ThinkPad T15 Gen 1 15.6" FHD Touch i5-10310U 40GB 1TB SSD laptop

ThinkPad T15 Gen 1 laptop

The Lenovo ThinkPad T15 Gen 1 is a 15.6-inch ultrabook built around a 10th Gen Intel Core i5-10310U quad-core processor. It ships with Windows 11 Pro and 40 GB of DDR4 memory configured as 8 GB soldered plus one 32 GB module. Integrated Intel UHD Graphics uses shared system memory for display output. The 1 TB M.2 2242 SSD provides the primary storage volume.

Build integration and expansion

The chassis offers one Thunderbolt 3 port, three USB-C 3.2 Gen 1 ports, HDMI 1.4b, Gigabit Ethernet and a 3.5 mm audio jack. A side docking connector supports compatible Lenovo docks for single-cable desk setups. Optional microSD, smart-card and WWAN slots may be present depending on the specific unit received. Memory slots are fully populated at 40 GB, leaving no free SO-DIMM socket for further upgrades.

Thermals, noise and power

The 1.7 GHz base processor can reach 4.40 GHz turbo under load while cooled by the internal fan assembly. Typical office workloads keep temperatures moderate and fan noise low. The included OEM AC adapter supplies power for charging and sustained operation. Integrated graphics and Wi-Fi 5 connectivity contribute to modest overall power draw during everyday use.
