About the ThinkPad X1 Yoga Gen 8
The ThinkPad X1 Yoga Gen 8 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 X1 Yoga Gen 8 is the 14 inch convertible in the X1 line. Lenovo publishes 13th Gen Intel U or P CPUs, soldered LPDDR5 / LPDDR5x up to 64GB, an M.2 2280 PCIe 4.0 x4 slot, and a WUXGA IPS or WQUXGA OLED touch panel. Aluminium top and bottom.
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. Lenovo publishes a 3-year onsite base term for this machine type, qualified as (1-yr battery) — the system is covered for three years, the battery for one.
Base warranty terms Lenovo publishes for ThinkPad X1 Yoga Gen 8 (21HQ):
- 1-year courier or carry-in service
- 1-year limited onsite service
- 3-year (1-yr battery) courier or carry-in service
- 3-year (1-yr battery) limited onsite service
- No base warranty
The 3-year onsite base term carries Lenovo's own (1-yr battery) qualifier verbatim: system three years, battery one. This is the standard PSREF wording for this generation of ThinkPad.
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.
Is the 3-year onsite base term real?
Yes. Lenovo publishes a 3-year (1-yr battery) limited onsite service option as one of the base warranty terms for this machine type. The battery is covered for one year under that term; the system is covered for three. See the Warranty and Service Cover accordion.
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.
