Technical Specifications
Technical Summary
This Wistron Hadley 15" motherboard, document number X02 revision A00, is built around the Haswell ULT 15W/25W CPU platform paired with a Lynx Point-LP PCH. The board number is 12311-1 with project code 91.47L01.001. Graphics are handled by an N14P-GT GPU with GDDR5 VRAM, and the system supports both UMA-only and Optimus dGPU configurations. The embedded controller is a Nuvoton NPCE985PA0DX in a W26 package, and the BIOS is stored on an 8MB Flash ROM. Audio is provided by a Realtek ALC3223 codec, while the charging architecture uses a BQ24717 charger IC with AD+BT+ input. Power management is handled by NCP81172, TPS51225, TPS51622, TPS51363, and TPS51216 DC/DC converters. Memory consists of two DDR3L 1600MHz slots arranged in Channel A and Channel B. The board integrates a Realtek RTL8411B combo LAN and card reader, a Realtek RTD2136R eDP to LVDS converter, a PERICOM PI5USB1457AZAE USB hub, and a Nuvoton NCT7718W thermal sensor.
