About the ThinkPad E16 Gen 1
The ThinkPad E16 Gen 1 is a Lenovo ThinkPad chassis built to the range's usual Singapore-market brief: MIL-STD-810H tested, discrete TPM 2.0, and Lenovo's ThinkPad keyboard and trackpoint layout. This exact part number is a specific factory build; the full option matrix Lenovo publishes for the machine type is in the Chassis and Platform section below.
Where this configuration sits in the range
The E16 Gen 1 is the 16 inch E-series business laptop on the Raptor Lake platform. Lenovo publishes 13th Gen Intel U/P/H CPUs, one soldered DDR4-3200 module plus one SO-DIMM, two M.2 2242 slots, and a WUXGA or WQXGA display. Note: the E-series PSREF publishes only 1-year base warranty terms for this machine type.
Who this configuration suits
Fleet buyers who need a specific, historically stocked configuration for parts continuity, image compatibility or a like-for-like replacement. For fresh purchases we usually recommend the current generation of the same chassis line — ask us for the equivalent and we will quote both.

Why This Page Shows Two Specification Groups
The This Configuration block above lists only what the store title asserts for this exact part number: processor, memory and storage. Anything more granular — exact panel, adapter, wireless card — is not asserted here because the distributor build-sheet copy that used to sit in this slot named a different Lenovo machine and could not be trusted for detail.
The Chassis and Platform block underneath quotes what Lenovo publishes for the whole machine type. It tells you what the chassis is capable of — the panels, ports, wireless cards, adapters and warranty terms that Lenovo enumerates — 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. If you need us to confirm a specific option is fitted to 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. For this machine type Lenovo publishes only 1-year base warranty options in PSREF, so the h2 above does not carry a 3 Years Onsite duration for this chassis.
Base warranty terms Lenovo publishes for ThinkPad E16 Gen 1 (21JN):
- 1-year mail-in service
- 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
- No base warranty
No 3-year onsite base term exists for this machine type. Lenovo publishes only 1-year terms. Any longer cover is a paid Lenovo Services upgrade, not a base term.
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 the Singapore-region base cover.

Questions We Get Asked About This Machine
Is this a Copilot+ PC or AI PC?
No. This machine type predates Lenovo's AI PC and Copilot+ PC classifications. Lenovo's PSREF book for this chassis does not publish an AI PC category field or an NPU TOPS figure.
Does this machine have a 3-year onsite base term?
No. Lenovo publishes only 1-year base terms for this machine type. A 3-year onsite claim on this chassis would not match Lenovo's own PSREF. See the Warranty and Service Cover accordion for the exact term list.
Is this the current generation?
No. This part number is at zero inventory and the chassis is past its launch generation. Ask us for a closely matching current-generation configuration.
