PDF schematic for the Dell Latitude 7280 laptop, built by Compal on the CAZ10 platform with board number LA-E121P, revision 0.1, archived as RAR. LA-xxxxP is Compal's standard motherboard numbering, and CAZ10 is the project code. The diagrams let a technician trace power rails, check the power sequence, locate test points and follow signal paths when chasing a short or a no-power fault. Revision 0.1 is an early issue, so compare the board number and revision silkscreened on the PCB before trusting component values.
