Zipped CAD boardview, 249 KB, covering the Compal LA-C621P mainboard used in the Dell Latitude E5270; it appears to be a duplicate copy of the same layout. Load the .cad file in OpenBoardView, FlexBV or a similar viewer to search part designators, highlight nets and see the location of test pads on both sides of the board. Compare the LA-C621P marking and revision silkscreened on your PCB first, since Dell often ships several Compal board variants under related models and placement can differ.
