Schematic for the Acer Aspire E5-551G on Compal board LA-B221P, revision 0.3, project code EA50_KV, in a 22.0 MB PDF. Because 0.3 is an early revision, some component values or layouts may differ from production boards, so cross-check with your PCB. Technicians use the pages to trace power rails, follow charging and power sequencing, locate the SPI BIOS chip and find causes of shorts. Any PDF viewer opens it. Compal LA numbers identify the board design, so confirm the code printed on your board.
