Schematic for a Compal-style board LA-4111P, revision 04 with the date code 0306, project JBL, UMA version, provided as a 14.9 MB PDF. The LA number pattern belongs to Compal, and UMA means integrated graphics rather than a dedicated GPU. No laptop brand is named, so match the board by its silkscreen. A technician uses these sheets to follow voltage rails, check the charger and power sequence, locate components and narrow down shorts. Revision differences can change parts, so compare the revision too.
