The planar board serves as the main logic board, integrating the processor, graphics, and memory subsystems into a single replaceable assembly. Based on the part number encoding, this board pairs an Intel Core i7-6800H series processor with an NVIDIA RTX 3060 discrete GPU carrying 6 GB of dedicated video memory and 6 GB of system RAM onboard. It is serviced by authorized technicians performing depot-level or advanced field repairs on compatible Lenovo mobile systems.\u003c\/p\u003e\u003cp\u003eThis planar board is intended for component-level repair scenarios where the existing board has failed due to GPU fault, processor failure, power delivery issues, or physical damage. Installation requires disassembly of the full chassis and is not a field-swappable part under normal circumstances. It is suited for authorized Lenovo service centers and experienced depot repair technicians working on the applicable mobile platform.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eIntegrated Intel Core i7-6800H series processor and NVIDIA RTX 3060 GPU on a single mobile planar assembly\u003c\/li\u003e\n\u003cli\u003e6 GB dedicated RTX 3060 graphics memory for compute and display workloads\u003c\/li\u003e\n\u003cli\u003e6 GB onboard system RAM included as part of the planar assembly\u003c\/li\u003e\n\u003cli\u003eOEM Lenovo replacement part ensuring compatibility with original firmware and thermal design\u003c\/li\u003e\n\u003cli\u003eDesigned for depot-level or authorized service repair workflows\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM replacement planar board for compatible Lenovo mobile systems. Consult the Lenovo parts lookup tool or service documentation using part number 5b21f65786 to confirm fitment for a specific model before ordering.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003ePlanar board replacement must be performed by a qualified technician with experience in mobile system depot repair. Power down the system completely, disconnect the battery, and discharge any residual voltage before beginning disassembly. Follow Lenovo hardware maintenance manual procedures for the specific chassis to avoid damage to flex cables, antenna leads, and thermal interface components. Reinstallation typically requires fresh thermal interface material on all processor and GPU contact surfaces.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eGPU\u003c\/strong\u003e: NVIDIA RTX 3060 6 GB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOnboard RAM\u003c\/strong\u003e: 6 GB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProcessor Series\u003c\/strong\u003e: Intel Core i7-6800H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eForm Factor\u003c\/strong\u003e: Mobile Planar Board\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: LENOVO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5b21f65786\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LENOVO","offers":[{"title":"Default Title","offer_id":51201676050738,"sku":"5B21F65786","price":1928.17,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307157921.jpg?v=1779697811","url":"https:\/\/voomisupply.com\/products\/lenovo-5b21f65786-mobile-planar-board-rtx-3060","provider":"Voomi Supply","version":"1.0","type":"link"}
