This assumes the “top” refers to either the of a power supply or the top-level sheet of a multi-page schematic. Adjust component references as needed based on the actual drawing.
Before diving into the top-level schematics, it is helpful to establish what hardware architecture the LA-D711P platform supports: lad711p rev 10 schematic top
The Dell Latitude 3480 and 3580 models are built on the Wistron Tiger-S (LAD711P) motherboard. For technicians and hobbyists, the "Rev 1.0" schematic is the roadmap required to navigate hardware failures, power sequencing issues, and component-level diagnostics.

is a Compal-manufactured motherboard designed to support AMD Bristol Ridge and Stoney Ridge APUs. Its "Rev 10" designation indicates it is a refined version of the board, likely addressing earlier issues in the design. It is known for its relatively straightforward architecture, making it a good subject for learning laptop repair. Compal LA-D711P Revision: 1.0 (Rev 10) Compatible Laptops: HP 15-BA, HP 15-AF, HP 15-AC series Adjust component references as needed based on the
