Technical Specifications
Technical Summary
This Wistron Loveland SKL-U motherboard (Board Number 14291, Revision A00) is built around the Intel Skylake U 2+2 CPU platform with a SKL PCH-LP. The graphics subsystem supports both UMA-only and discrete NVIDIA N16V-GM-S OPTIMUS configurations, with documented conversion capability between UMA and DIS modes. System memory consists of two DDR3L SODIMM slots supporting up to 1600 MHz. The embedded controller is an NPCT650JAAYX92 with a 16MB SPI Flash ROM for BIOS and EC firmware storage. Power management is handled by a BQ24780RUYR battery charger and multiple DC/DC converters including NCP81253, SY8208, RT6576, NCP81208, NCP81382, M5938, and TPS51716. Audio is provided by a Realtek ALC3246 HDA codec. Networking includes a Realtek RTL8111G Gigabit LAN and an Intel AC 3160 wireless combo module. A Realtek RTS5170 card reader, Realtek RTD2168-CGTDP VGA converter, and MEC1404 thermal sensor complete the peripheral set.
Technician FAQ
Q: What BIOS/EC flash configuration is used on this motherboard?
A: The motherboard uses a single 16MB SPI Flash ROM for both BIOS and EC firmware storage, with the EC being an NPCT650JAAYX92.
Q: Does this motherboard support dGPU to UMA conversion?
A: Yes. The schematic explicitly documents both UMA-only and DISCRTE OPTIMUS installed configurations
