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 variants 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 variants
- 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 functionality 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 variants. 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.

Performance & Real-World Use
In our experience testing hundreds of ThinkPad boards, the i7-1185G7 Tiger Lake platform handles enterprise workloads reliably — Teams calls, multi-document editing, and concurrent remote desktop sessions run without bottlenecks. The integrated Intel Iris Xe (96 EU) handles 1080p video playback and light graphical tasks smoothly. Tested February 2026, this configuration remains a capable and cost-effective repair choice for enterprise ThinkPad T14 and T15 Gen 2 fleets through 2027 and beyond.
Operating System & Platform
This board carries the Windows platform flag (WIN), configured for Windows deployment. The i7-1185G7 supports both Windows 10 and Windows 11, and TPM 2.0 is present on this platform — therefore rebuilt units meet Windows 11 upgrade requirements, which means repaired devices retain a supported OS lifecycle rather than being locked to Windows 10's end-of-support timeline.

Refurbished Computers - Cosmetic Grading Guide
Our supplier's refurbished hardware is typically graded either "Excellent" or "Good", however, some legacy products were graded under a letter grading system (A, B, C). Please find the definitions for each grade below and contact us if you're uncertain of a device's grade.
Used Smartphone / Refurbished Mobile Phones
"Excellent" Grade
Devices in this category appear like new, with very minor wear. Expect light or fine scratches on the screen that are shallow enough not to catch on a fingernail. The edge around the glass is virtually flawless, save for possible light scratching around the power port. The back plate may show light/fine scratches, including on the Apple logo, with any discoloration being minimal.
"Good" Grade
These devices are characterized by being fully tested and functional even if they have body scratches, minor paint chips, or a small hairline crack on the screen. Screens are free from dead pixels but may exhibit slight scratching from moderate use.
Refurbished Desktops, Laptops and Monitors
"Excellent" Grade - Laptops
Reserved for units that show barely any signs of previous use, these laptops may exhibit very minor scuffing or abrasions, associated only with minimal standard use. The keyboards show light wear, and importantly, the screens are pristine, free from any scratches, cracks, chips, dead pixels, dark spots, discoloration, or blemishes.
"Excellent" Grade - Desktops
Desktop PCs in the "Excellent" grade category are free from deep scratches, cracks, paint chips, or any broken/missing pieces, ensuring a sleek and almost-new aesthetic.
"Excellent" Grade - Monitors
"Excellent" grade is reserved for units that show evidence of very little to no previous use. Any wear on an "Excellent" Display, including housing/frame and/or external surfaces (i.e. Frame) is associated with standard minimal use. "Excellent" units may have minor scuffing and / or minor abrasions on plastics with from standard light previous use."Excellent" Displays will feature no scratches, cracks, chips, dead pixels, dark spots, discoloration or blemishes. Units will only feature the standard minimal wear and tear that is associated with a used unit.
"Good" Grade - Laptops
"Good" laptops may feature one or several small dings or dents on covers and / or small paint chips on the surface or small hairline cracks in the bezel. Laptop screens may feature uneven light diffusion in screen and may feature subtle blemishes. "Good" Laptops will not feature cracks screens but may feature slight scratching, dead pixels or white spots on the screen.
"Good" Grade - Desktops
"Good" grade desktops may have light scratches on external body and may feature more excessive unit housing and/or external case wear than "Excellent" units, including wear on case / lid. "Good" PCs may feature one or several small dings or dents on covers and / or small paint chips on the surface.
"Good" Grade - Monitors
Displays in the "Good" grade have been fully tested and are functional but may include scratches on body, small paint chips, minor cracks on body, loose and/or wobbly bases. "Good" Display screens may feature uneven light diffusion in screen and may feature subtle to moderate blemishes. "Good" Displays will not feature cracks on screens but may feature slight scratching on screen surfaces from moderate use or wear, dead pixels or white spots on the screen.
