Boardview for the Dell Inspiron 15 3576, built on Wistron design Vegas Turis MLK KBL-R, board 17841-1, packed in a 304 KB ZIP. KBL-R points to Intel Kaby Lake Refresh CPUs, and the 17841-1 code follows Wistron's numbering for boards it builds for Dell. Load it in FlexBV or OpenBoardView to locate components, follow nets and find test points, ideally alongside the matching schematic. Check the board number on the PCB before use, because Dell models often have several board variants.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @cynetitsolution. Enginerys does not host this file.
