Schematic set for the Dell Latitude E5270 (written E520 in the name), E5470 and E5570 and the Precision 3510, which share Compal boards. The listed numbers are LA-C621P and LA-C641P, and the index also links LA-C642P and LA-C631P. The 2.85 MB RAR is useful for tracing power rails, the charging circuit and the EC power-on sequence. Find the page for the board number on your PCB, because subboards and variants differ.
