Product Description

The LENOVO 5b20s44398 is an OEM system board designed as a direct replacement for Lenovo laptop platforms carrying the 81X3 board identifier. It integrates an Intel Core i7-1065G7 processor, a 10th-generation Ice Lake quad-core chip with a base clock suited for mobile computing workloads. The board also includes a discrete GPU configuration and supports 16GB of onboard memory. This is a factory-sourced component intended for depot-level or advanced component-level repair of Lenovo consumer and commercial laptops in the 81X3 product family.

This board is suited to professional repair technicians performing depot or bench-level motherboard replacement on affected Lenovo laptop units. The 81X3 designation corresponds to a specific Lenovo laptop model series. The board comes configured with Windows compatibility and is paired to the discrete graphics path, making it appropriate for units that originally shipped with a dedicated GPU rather than integrated-only graphics. Technicians sourcing this part should verify the exact model identifier of the failed unit before ordering to confirm fitment.

Installation Notes

Motherboard replacement on laptop systems is a depot-level repair performed by qualified electronics or computer service technicians. Power down the unit completely, disconnect the battery, and discharge any residual capacitance before handling the board. Anti-static precautions are required throughout the procedure. Do not attempt installation without appropriate disassembly documentation for the specific Lenovo model, as connector and fastener locations vary by chassis.
