Technical Summary

This Compal HGT30/31 LA-3061 Rev 0.1 motherboard is built around the Mobile Yonah uFCPGA/uFCBGA-478 CPU platform with Intel Calistoga GM/PM and ICH7-M core logic. The graphics subsystem features an Nvidia G72/G73 dGPU connected via PCI-E x 16, with 128/256MB VRAM. System memory consists of two DDR2-SO-DIMM slots supporting dual-channel DDR2-400/533/667. The embedded controller is an ENE KB910/L. Audio is handled by an AD1986A codec. The charging circuit uses an MB39A126 charger IC with an AO4407 MOSFET, while power management is managed by MAX8770, MAX8734AEE, ISL6269CRZ, APL5912-KAC, APL5331KA, and SI9182DH regulators. Networking is provided by a Realtek RTL8110CL/SBL LAN controller. The board includes an ADM1032 thermal sensor, an R5C832 card reader, and a CB1410 USB hub controller.
