La-e801p Rev 2.0 Schematic !exclusive!

Based on the technical documentation for the Compal LA-E801P (Rev 2.0) motherboard (commonly found in the Dell Latitude 5289 2-in-1), Core Architecture

Keywords used: la-e801p rev 2.0 schematic, Dell Vostro 14-3458 motherboard, boardview file, laptop power sequence, IT8528 EC, RT8248 power IC la-e801p rev 2.0 schematic

  • Schematic (.pdf): Circuit diagram, voltages, signal names.
  • Boardview (.brd or .cad): Shows exact component locations on the PCB. Use OpenBoardView (free) to open it.

Voltage Injection: If the schematic shows a short to ground on a main rail like +1.0V_MCP, use the schematic to find a safe injection point to identify the heating component. Safety Warning Based on the technical documentation for the Compal
