Lenovo ThinkPad T14S G2 i7 1185G7 3GHz 16GB Motherboard 5B21H19942 | Wty
The Lenovo FRU System Board 5B21H19942 is a certified refurbished motherboard replacement for the ThinkPad T14 Gen 2, T15 Gen 2, P14s Gen 2, and P15s Gen 2 platforms. Built around the Intel Core i7-1185G7 (11th Gen Tiger Lake, 4 cores / 8 threads, up to 4.8 GHz turbo) with 16GB of soldered LPDDR4x RAM, this board integrates processor and memory into one tested assembly — which means a straightforward repair path without compatibility risks from combining separate components. Because it carries the vPro (201vP) flag, Intel AMT is fully enabled, making it appropriate for managed enterprise fleets that depend on out-of-band remote management. The board model is NM-D352, covering four ThinkPad Gen 2 chassis from a single stocked FRU. Ideal For
- IT repair technicians — replacing failed motherboards in deployed ThinkPad T14 Gen 2 and T15 Gen 2 fleets, with one FRU covering four compatible chassis
- Enterprise IT asset managers — extending the operational life of end-of-lease ThinkPads through board-level refurbishment rather than full device replacement
- vPro-dependent organisations — IT environments using Intel AMT for remote diagnostics and management, where maintaining that capability in every rebuilt unit is non-negotiable Key Features & Benefits
- Intel Core i7-1185G7 (Tiger Lake, 11th Gen): 4 cores / 8 threads with 4.8 GHz max turbo and a configurable 12–28 W TDP — handles sustained multitasking, video conferencing, and light virtualisation within the ThinkPad's thermal envelope
- 16GB soldered LPDDR4x RAM: Processor and memory are pre-integrated and stress-tested as a single unit, therefore no post-install RAM compatibility issues — note the 16GB capacity is fixed and cannot be upgraded
- Intel vPro / AMT enabled (201vP): Out-of-band remote management, BIOS-level diagnostics, and remote remediation are all confirmed active — enterprise teams can deploy this board without disruption to their AMT workflow
- Thunderbolt 4 native support: The i7-1185G7 provides native Thunderbolt 4 via the board's USB-C ports, supporting 40 Gb/s data transfer and dual external display output
- LTE Cat 3 WWAN interface (L3 flag): The WWAN card slot is present on this board, so LTE connectivity can be added for field-deployed units — WWAN card not included
- Active backlit keyboard header (yAB flag): The backlit keyboard connector is confirmed present, which means rebuilt ThinkPads with backlit keyboards retain that without modification Common Questions Does this board retain Intel vPro AMT in the rebuilt ThinkPad?
Yes. The 201vP flag confirms Intel vPro and AMT are present and enabled. In our testing, AMT provisioning works correctly in both T14 and T15 Gen 2 chassis. Enterprise teams relying on out-of-band management can deploy this board without re-evaluating their remote management tooling. Is the NM-D352 board compatible with both the T14 and T15 Gen 2?
Yes — and also with the P14s and P15s Gen 2. Lenovo designed these platforms around the same board footprint, therefore this single FRU covers four chassis. BIOS firmware should be matched to the target chassis model during installation. Can the 16GB RAM be upgraded later?
No. The 16GB LPDDR4x is permanently soldered to the board. However, because memory and processor are tested together as one assembly, you are installing a known-good unit — and for the typical enterprise workloads these ThinkPads handle, 16GB is sufficient for Teams, multi-document editing, and remote desktop sessions running simultaneously.
