This board, manufactured by Compal (the OEM behind many Dell boards), features the 8th Generation Intel Kaby Lake R (Whiskey Lake) platform. It is notorious for specific power delivery issues, BIOS corruption, and burnt MOSFETs. Whether you are facing a "no power," "no display," or "power cycling" fault, having the correct Rev 2.0 schematic is the difference between a successful repair and scrapping the board.
: Supports Intel Core i3, i5, and i7 processors, often paired with an AMD R17M discrete GPU and DDR4 SO-DIMM memory. Key Power Rails : +19.5VB (Main Rail) : The primary input from the adapter.
Pin-out definitions for the LVDS/EDP display connector, keyboard interface, and BIOS/EC (Embedded Controller) chips.
Almost every schematic starts with a Block Diagram.
