Dell Inspiron 7590 Wistron WHL 18718-1 Schematic
Technical Specifications
Technical Summary
This Wistron Jedi 15"/17" motherboard (board number 18718, project code 4PD0GE010001, revision X02) is built on the Intel Whiskey Lake-U platform with a discrete NVIDIA N17S-G1 GPU featuring 2GB GDDR5 VRAM. The system uses a 16MB Quad Read Flash ROM for BIOS/SPI storage. Embedded controller functionality is provided by a NUVOTON NPCT750 and ST33HTPM. Audio is handled by a Realtek ALC3254-VA3 codec. The board supports DDR4 SODIMM memory across two slots (Channel A and B). Power delivery includes a TPS65982D charging IC. Thermal monitoring is managed by a NUVOTON NCT7718W sensor. Connectivity includes a Realtek RTS5100 card reader, Intel I219-V LAN, Intel CNVi WLAN, and a Parade PS1752-1 HDMI level shifter.
