lenovo g570 compal piwg1-piwg2 la-6751p la-6753p-rev0.3 schematic
Technical Specifications
Technical Summary
This Compal LA-6751P / LA-6753P schematic documents the Lenovo G470 and G570 motherboards, built on the Intel Sandy Bridge processor platform with a Socket-rPGA988B CPU socket and Intel Cougar Point PCH. The graphics architecture supports DIS+UMA+Muxless configurations using an AMD Robson XT GPU. System memory consists of dual-channel DDR3 via two SO-DIMM slots. The embedded controller is an ENE KB9012 or ENE KB930, and the audio subsystem is handled by a Conexant CX20671 codec. Wired networking is provided by an Atheros AR8151-B or AR8152-B LAN IC, and a Realtek RTS5139 card reader IC is present. Thermal monitoring is managed by an EMC1403 sensor. The BIOS is stored on a SPI ROM.
