lenovo thinkpad l421 gc9f quanta dm4 rb4 schematic 1
Technical Specifications
Technical Summary
This Quanta Computer Inc. DM4/RB4 project is an Intel Huron River Platform motherboard featuring a Sandy Bridge CPU in an rPGA 989 socket paired with a Cougar Point PCH. The platform supports discrete graphics and dual-channel DDR3 memory via two SODIMM slots. System management is handled by an IT8518 EC/KBC, while audio is provided by an ALC269 codec. The board utilizes two SPI flash devices for BIOS storage, a 2Mbyte and a 4Mbyte. Charging is managed by an ISL88731 charger IC, and wired networking is supported by a Realtek RTL8111DL(VB) LAN controller.
