Worth knowing about this configuration
Processor: the store title says Core Ultra 7 255U while the build sheet says 255H. Lenovo publishes both for this machine type, so both are legitimate configurations — confirm which is being quoted.
21SACTO1WW is Lenovo’s configure-to-order bucket identifier for the machine type rather than a finished-goods part number.
Why This Page Shows Two Specification Groups
The This Configuration block lists what the store title and the distributor build sheet assert for this exact part number: processor, memory, storage and the per-unit options. The Chassis and Platform block underneath quotes what Lenovo publishes for the whole machine type — the panels, ports, wireless cards, adapters and warranty terms the chassis is capable of — without claiming any single row was fitted to this particular unit.
Reading them side by side is how the storefront tells a part-specific fact apart from a chassis-wide capability. Where the two sources disagree, both are shown and attributed. If you need us to confirm a specific option on this exact part number, ask and we will check with the distributor.
Warranty and Service Cover
Every SourceIT unit is supplied with Singapore local warranty.
The distributor build sheet for this configuration documents a 3-year onsite service level. Lenovo's own base term for this machine type differs — Lenovo publishes a 3-year onsite option qualified (1-yr battery): the system is covered for three years, the battery for one.

- 1-year courier or carry-in service
- 1-year courier or carry-in with 2-year system board service (Korea only)
- 1-year limited onsite service
- 3-year (1-yr battery) courier or carry-in service

Questions We Get Asked About This Machine
Is this an AI PC or a Copilot+ PC?
Lenovo classifies this machine type as an AI PC (Intel AI Boost, up to 12 TOPS). It is not a Copilot+ PC — that classification needs a 40+ TOPS NPU, which this platform does not reach.
Can the memory be upgraded?
Yes. Memory is on SO-DIMM slots (up to 64GB (2x 32GB)), so it can be upgraded later.
Is the three-year cover real?
Yes — it is documented on the distributor build sheet for this configuration. See the Warranty and Service Cover section for exactly what Lenovo publishes as the base term versus the configured upgrade.
