Schematic diagram in PDF for Compal board LA-E541P, revision 2.A, with project codes DIUYA YB, SA, SB and SD and a Kaby Lake-R (KBL-R) platform noted in the name. LA-xxxxP is Compal's ODM numbering, used on laptops of several brands. Technicians open it in any PDF viewer to follow power rails, the power-on sequence, charger and signal paths, and to find component values when tracking a short or a missing voltage. Confirm the LA number and Rev 2.A on the PCB, since other revisions can differ in part placement and values.
