Lenovo 5b21k93268 Planar Board I5-1145g7

Product Description

The LENOVO 5b21k93268 is a planar board (system board) engineered for Lenovo computing platforms running Windows and equipped with an Intel Core i5-1145G7 processor configuration. The planar board serves as the main logic board, providing the foundational circuitry that connects the processor, memory, storage interfaces, and I/O subsystems within the host unit. This part is a factory-level Lenovo component intended for technicians performing depot-level board swaps or motherboard-level repairs on compatible Lenovo systems. The i5-1145G7 designation indicates this board is paired with or designed around that specific Intel 11th Generation Tiger Lake processor.

This planar board is suited for board-level replacement work on Lenovo notebook or compact computing platforms that originally shipped with the Intel Core i5-1145G7 processor and a Windows operating environment. Installation is appropriate in depot repair, warranty service, or authorized service center contexts where a failed or damaged system board requires replacement. Technicians should confirm the host unit model and board revision before ordering to ensure a proper fit.
