Dell Latitude E5450 schematic in PDF format for the LA-A901P motherboard, revision r03, with the platform project name ZAM70 in the title. LA-xxxxP numbering is the Compal pattern, so Compal designed and built this Dell board. The 1.88 MB document covers power rails, the charging circuit, CPU supplies and peripheral interfaces, making it useful for tracing a missing voltage or a short to ground. Read it in any PDF viewer and make sure the LA number and revision on the PCB agree with this drawing before working from it.
