Product Name & Key Specifications
Certified Refurbished Lenovo ThinkPad L13 Gen 1 / L13 Yoga Gen 1 System Board (FRU 5B20W77264) integrates an Intel Core i5-10310U vPro CPU with 16GB DDR4 (8GB + 8GB) soldered RAM, supports M.2 NVMe SSD storage, and is designed for a 13.3-inch ThinkPad L13/L13 Yoga chassis. Because the processor and memory are on the board, this is the right part when you’re repairing a no-power fault, intermittent boot issues, or liquid-damage failures where the mainboard must be replaced rather than “fixed”. In practical terms, it restores the full platform—USB-C docking, Wi‑Fi, display output, and onboard security features—so the laptop can go back into daily service for office workloads in 2026.
Ideal For
This system board is a good fit for:
- IT repairs and fleet maintenance - Replacing a failed motherboard in ThinkPad L13 Gen 1 / L13 Yoga Gen 1 units to keep standardised deployments running.
- Businesses using remote management - The i5-10310U vPro platform supports enterprise manageability features, which helps with remote support and device oversight.
- Users needing a complete mainboard solution - When CPU and RAM faults are suspected, a board swap resolves multiple potential failure points in one step.
Key Features & Benefits
- Intel Core i5-10310U (4C/8T) integrated: Because it’s soldered to the board, you’re replacing the entire compute platform at once, which reduces compatibility guesswork during repair.
- 16GB dual-channel soldered memory (8GB + 8GB): This configuration suits heavy browser + Teams + Office multitasking, however it is not upgradeable because there are no RAM slots.
- UMA Intel UHD Graphics: Handles everyday productivity and smooth 1080p playback, which means it’s ideal for office and study workloads rather than gaming.
- ThinkPad L13/L13 Yoga Gen 1 connectivity support: Designed for the platform’s typical USB-C features (including docking capability where supported by the chassis configuration), plus standard laptop I/O and internal connectors.
Common Questions
Will this board let me upgrade the RAM later?
No—this model has 16GB soldered (8GB + 8GB) and no RAM slots, therefore what you buy is what you run for the life of the device.
Is this the right part for my ThinkPad L13?
It’s designed for ThinkPad L13 Gen 1 (type 20R3/20R4) and L13 Yoga Gen 1 (type 20R5/20R6). If you’re unsure, match your machine type and existing FRU/part number before purchase, because Lenovo often has multiple sub-FRU variants.
Can it handle video calls while multitasking?
Yes for typical office use—an i5-10310U with 16GB dual-channel memory is well suited to Teams/Zoom plus multiple documents and many browser tabs, which means the system stays responsive provided you pair it with an NVMe SSD and a clean Windows install.

Performance & Real-World Use
In our workshop experience, ThinkPad L-series mainboard replacements are most often chosen when a fault is board-level (no power, random shutdowns, liquid corrosion, or damaged USB-C power circuitry), because repair time can exceed the value of the unit. With the i5-10310U and 16GB dual-channel memory, this 2020-era platform remains very capable for 2026 everyday computing—especially when paired with an NVMe SSD and current drivers.
Operating System
This board is intended for Windows-based ThinkPad deployments. Pros: Strong compatibility with business applications and ThinkPad utilities, therefore support and driver availability is straightforward. Cons: Windows performance depends heavily on SSD quality and having a clean install (background bloat can make any system feel slower).
Cosmetic Condition Guide
This is an internal component, so cosmetic grading is generally less relevant than with laptops and screens. If supplied as part of a complete refurbished device, Excellent Grade typically shows only minor signs of use, while Good Grade shows more visible wear such as light scratches or scuffs while remaining fully operational.
Verified Reboot Refurb Quality Assurance
Every unit is verified refurbished by Reboot IT through a structured process including diagnostic checks, functional testing of key components and ports, cleaning, and verification steps designed to confirm reliable working condition before sale.
Warranty & Support
This certified refurbished product is sold by Reboot IT and includes a 1 year warranty for your peace of mind.

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.
