About the ThinkPad E14 Gen 5
The ThinkPad E14 Gen 5 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 E14 Gen 5 is a 14 inch E-series business laptop on the Raptor Lake platform. This factory build pairs an i5-1335U CPU with 8GB soldered DDR4-3200 and a 512GB M.2 2242 NVMe SSD. Note: Lenovo publishes only 1-year base warranty terms for MT 21JK.
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 is drawn from the distributor build sheet for this exact part number — the panel, processor, memory, storage, wireless card and adapter actually fitted.
The Chassis and Platform block underneath quotes what Lenovo publishes for machine type 21JK as a whole. It tells you what the chassis is capable of — the panels, ports, wireless cards, adapters and warranty terms that Lenovo enumerates — without asserting each row is fitted to this unit.
Reading them side by side lets you tell what the shipped part number actually is apart from what the chassis supports as an option. If a spec you need is in the chassis list but not the configuration list, ask us and we will check 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 E14 Gen 5 (21JK):
- 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.
