Compal LA-3801P schematic for the Dell Latitude E6400 laptop, project JBL00, in a 1.41 MB RAR. This is a different board revision from the JBL01 LA-3803P design, so confirm which number your mainboard carries before tracing circuits. Compal LA numbering appears on many Dell business notebooks. The PDF helps technicians map power rails, locate the EC, charger and voltage regulators, and follow signal paths when a board will not power on or charge. Extract the archive and open the PDF in any standard viewer.
