Lad711p Rev 10 — Schematic Top
The (commonly known by its platform name BDL51 ) is a widely distributed OEM laptop circuit board manufactured primarily for the popular HP 15-BA, 15-AY, and 15-BA000 series notebook computers. When a laptop built on this architecture suffers a critical hardware failure—such as failing to turn on, showing a black screen, or getting stuck in a boot loop—technicians and micro-soldering engineers rely strictly on the LA-D711P Rev 1.0 schematic to trace power rails, isolate short circuits, and identify failing logic gates.

If a short is found on DCBATOUT, use a DC power supply to inject 1V and use thermal imaging or isopropyl alcohol to find the heating component. Schematic Symbols and Layout Navigation
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.
: Repair technicians frequently use the schematic for the LA-C801P as a reference, as Compal platforms from this era often share nearly identical power sequences and component positioners. The Primary Rail (+B / +19V) : Controlled
