Lenovo ThinkPad Z16 AMD Ryzen 7 PRO 6850H/ 16GB/ 512GB SSD
PRODUCT DESCRIPTION
Lenovo ThinkPad Z16 Gen 1 (AMD), AMD Ryzen 7 PRO 6850H, 16GB soldered onboard memory, 512GB SSD (build sheet: M.2 2242; Lenovo PSREF publishes M.2 2280 for this machine type) (21D4002WSG) — Singapore Local Warranty
Listing correction. Lenovo’s own name for this machine type (21D4) is “ThinkPad Z16 Gen 1.” There is no ThinkPad Z16 Gen 3 in Lenovo’s catalogue; Z16 Gen 2 is a separate, later machine type. The store title should read Z16 Gen 1.
Stock status. This exact part number is currently at zero inventory. It is still active while stock lasts, and we can offer a closely matching current-generation configuration on request.
About the ThinkPad Z16 Gen 1 (AMD)
The ThinkPad Z16 Gen 1 (AMD) is a Lenovo ThinkPad built to the range's usual Singapore-market brief: MIL-STD-810H tested, discrete TPM 2.0 hardware security, 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 ThinkPad Z16 Gen 1 (AMD) runs on the ThinkPad Z16 Gen 1, AMD Ryzen PRO 6000 series (Rembrandt) platform. Lenovo publishes no AI PC or Copilot+ PC classification for this machine type — it predates that scheme. Memory is soldered to the board with no slots, so it cannot be changed after purchase. One M.2 2280 slot, PCIe 4.0 x4, Opal 2.0; up to 2TB. It has no onboard Ethernet; wired networking uses a USB-C adapter or a dock.
Who this configuration suits
Fleet buyers who need this 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 and we will quote both.
Specification note. This page lists the configuration named in the store title and the distributor build sheet, and separately shows Lenovo's published chassis facts for machine type 21D4. Where the two sources differ, both figures are shown and attributed; anything neither source states is marked not stated rather than estimated. Specifications and prices are subject to change by Lenovo without notice.

Worth knowing about this configuration
Memory: the build sheet states LPDDR4X-6400; Lenovo PSREF publishes LPDDR5-6400 for this machine type. Both are shown.
Storage form factor: the build sheet states M.2 2242; Lenovo PSREF publishes M.2 2280 for this machine type. Both are shown.
Lenovo’s 135W adapter is the published charger for this machine; the build sheet’s 65W figure is shown but may understate the shipped adapter.
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 Z16 Gen 1 (AMD):
- 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
- 3-year (1-yr battery) limited onsite service
- No base warranty
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?
No. This machine type predates Lenovo's AI PC and Copilot+ PC classifications, and Lenovo's book publishes no AI PC category or NPU TOPS figure for it.
Can the memory be upgraded?
No. Memory is soldered to the system board with no slots, so the fitted capacity is fixed for the life of the machine. Choose the capacity you need at purchase.
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.
