Worth knowing about this configuration
The build sheet for this SKU omitted the display line; the panel shown is the machine type’s published WUXGA 400-nit panel. Ask us to confirm the exact panel on this unit.
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.
Lenovo's published base warranty for this machine type is one year (courier, carry-in or onsite depending on the term chosen). Lenovo's book also lists a 3-year onsite option qualified (1-yr battery), but the build sheet for this configuration does not document that upgrade, so we make no three-year claim here. Ask us to quote a Lenovo warranty upgrade if you need one.
Base warranty terms Lenovo publishes for the ThinkPad L14 Gen 5 (Intel):
- 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

PSREF does not enumerate Premier Support for this chassis; Premier Support and warranty upgrades come from separate Lenovo Services SKUs and are quoted on request. Register the serial number on Lenovo Support after purchase to activate Singapore-region cover.

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 11 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.
What is the warranty?
Singapore local warranty. Lenovo's published base term for this machine type is one year; a three-year onsite upgrade is available to quote. See the Warranty and Service Cover section.
