At Reboot IT, we adhere to strict quality guidelines, ensuring that our refurbished products are not the same as used or secondhand items. We meticulously clean, test, and assess each device, replacing worn parts with high-quality components.
Unlike used items, which lack guarantees and rely solely on the seller's word regarding condition, refurbished devices come with assurance of quality and reliability.

Description
Description
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.

Good value and great quality
Fantastic service
I was looking for an in-expensive all-in-one solution for my home office to replace my existing desktop and monitor. I found this EliteOne 800 on reboot IT for under $200. I wasn't sure what to expect. It arrived within two days!!!! I upgraded the RAM, replaced the HDD and installed Windows 11. This is unbeatable value and was the cheapest price online. Coupled with a 3-month warranty, Reboot IT are by far the best online refurbished retailer I have used. Awesome!
Great service. Product in great condition and exactly what i want. I wanted this for a specific purpose but i dont need to spend $900 on a new one.
Excellent work
exactly as described and works well , just like the staff down there. 10/10
Very happy, thank you
Just having trouble greeting it linked to the internet otherwise it’s okay.
Fair tech for price, good specs for era, serves the purpose. The black keyboard is an interesting rubber like texture clearly by design to pad the screen and avoid the keyboard touching. Screen is great. Still looking for magic formula to enable computer use in the bright bright sunshine. Keyboard taps are loud for someone who likes silent touch. The perfect PC has to exist, like build a bear.
The laptop was sold with a warning about worn keycaps. In fact they had been obviously vandalised (ex school laptops, perhaps?). The keyboard worked fine, and the rest of the laptop too. I'm using it as a file server, so I don't need the keyboard much. So very pleased, and also pleased with reboot-it's service - as always, excellent, and quick responses to any queries.
Great way to buy a computer
Always good, sometimes a little slow and steady, but always good :-))
I needed a quick cheap windows 11 capable notebook.
RebootIT had a bunch of 2nd hand stuff advertised.
This Dell 5310 was one of them, at the right price and spec.
It works brilliantly, although its not the prettiest notebook I've seen.
RebootIT were up front about the condition though, so I still got a better notebook than I expected.
Perfect thin monitor for my purposes.
Unit was in excellent condition as described. Dispatch was priority and prompt.
Just plain good old fashion service. Nothing more to say I guess
