Built for business mobility

The Lenovo ThinkPad T15 Gen 1 is a 15.6 inch ultrabook with a 1920 x 1080 IPS touchscreen. It runs Windows 11 Pro on a 10th Gen Intel Core i5-10310U quad-core processor with 16 GB DDR4 memory and a 1 TB M.2 2242 SSD. Integrated Intel UHD Graphics handles everyday visual tasks.

Thermals and power profile

The low-voltage i5-10310U operates at a 1.7 GHz base with a 4.40 GHz turbo, keeping heat and fan noise modest during typical office workloads. Shared system memory for graphics reduces discrete component power draw. The included OEM AC adapter supplies charge for the 3-cell battery during extended sessions.

Connectivity and daily workflow

Three USB-C 3.2 Gen 1 ports and one Thunderbolt 3 port provide flexible docking and peripheral options. A single HDMI 1.4b output, gigabit RJ-45 Ethernet and a 3.5 mm headset jack cover external displays and wired networks. Memory is configured as 8 GB onboard plus 8 GB in the sole slot, leaving no free DIMM for future expansion.

Questions about this item

How do I add more memory to the T15 Gen 1 and which slot do I use?

The laptop has 16 GB total — 8 GB soldered and one 8 GB DDR4 2666 module in the single SO-DIMM slot. To increase capacity you must remove that module and fit a larger one; the board supports up to 48 GB.

Which parts are likely to need replacement first on this ThinkPad?

The 1 TB M.2 2242 SSD and the internal battery are the only user-replaceable components that wear out. The memory slot is already occupied, so a future upgrade means swapping the existing DDR4 stick.

What thermal limit appears first when the i5-10310U runs at 4.40 GHz for a long time?

The 15 W sustained power envelope of the quad-core U-series chip is reached before the cooling system can dissipate more heat, so clocks drop to stay within that envelope.
