Combined package for Wistron board 17879-1B, project code CHEWBACCA 14, a Kaby Lake Refresh design in the UMA (integrated graphics) version. The name says it holds both a PDF schematic and a CAD boardview, making it a full repair set. Five-digit Wistron numbers with a dash and suffix mark the design and revision. Use the schematic to trace rails and power-on sequencing and the boardview in OpenBoardView or FlexBV to find parts. Confirm the board number and that your unit has no dedicated GPU.
