Lenovo Ideapad Gaming 15IAH7 LA-L911P Schematic
Technical Specifications
Technical Summary
This Compal LA-L911P schematic, revision 1.0 dated November 11, 2021, documents a motherboard designed for the Intel Alder Lake-H45 processor platform. The CPU is an Alder Lake-P (H45) BGA1744 Type3 45W 6C 8A + GT. Graphics are handled by an Nvidia GPU, specifically the GN20-P0 (RTX 3050) or GN20-P1 (RTX 3050 Ti). The embedded controller is an IT8176 MCU with keyboard controller. System memory consists of DDR4 3200MHz, configured as one DDR4 SO-DIMM slot plus four B-ch memory down chips. The primary BIOS SPI flash is an 8MB W25Q16JWSSIQ, with a compatible model listed as W25R256JVEIQ. A separate EC flash ROM, the W25Q80DVSSIG, is also present. The charging architecture uses a TPS65993AEA Power Delivery controller. The audio codec is a Realtek ALC3287, and the LAN controller is a Realtek RTL8111H-CG. The board also features a PS8719B USB hub IC and a KB9542Q card reader controller.
