ThinkPad T15 Gen 1 15.6" FHD non-touch

The Lenovo ThinkPad T15 Gen 1 is a 15.6 inch business laptop with a 1920 x 1080 IPS panel and a quad-core Intel Core i5-10310U processor. It ships with 16 GB of DDR4 2666 memory and a 1 TB M.2 2242 SSD, running Windows 11 Pro out of the box. Integrated Intel UHD Graphics use shared system memory for everyday visual tasks.

Upgrade from dual-core or 8 GB systems

Moving from a dual-core ultrabook or an 8 GB configuration gives a clear jump in multi-thread throughput and headroom for simultaneous workloads. The four cores reach 4.40 GHz turbo, so compile jobs, heavy spreadsheets and virtual machines finish faster. The single memory slot is already populated, so further RAM expansion requires replacing the module rather than adding a second stick.

1 TB SSD and 48 GB memory ceiling

The 1 TB drive holds large project libraries, local databases and offline media without constant cleanup. Memory can scale to 48 GB for developers running containers or analysts loading wide datasets, though the soldered 8 GB plus one removable stick limits upgrade paths. Integrated graphics and Wi-Fi 5 cap external GPU use and high-density wireless environments.

Questions about this item

What drive size fits the single M.2 2242 slot in this T15 Gen 1?

The laptop accepts one M.2 2242 SSD up to 1 TB, which is the size already installed.

How is the M.2 2242 SSD installed, and what step is often missed?

Remove the base cover, insert the drive into the slot, then secure it with the retention screw — the screw is the step most often forgotten.

What memory upgrade path exists later, given the current 16 GB DDR4 2666 configuration?

Eight GB is soldered and one slot holds an 8 GB module; max supported is 48 GB, so replacing the module with a 40 GB stick is the only way to add capacity.
