Acer Aspire E1-472 laptop schematic in PDF form, labelled EA40-HW with the number 12243 in the name. EA40-HW is the design project code, and 12243 looks like a Wistron-style board number, though confirm it against the PCB silkscreen. With the document a technician can trace rails from the DC input through charging and regulators, inspect the power-on sequence and find parts linked to a shorted net. Any PDF viewer will open it; verify the board revision before trusting component values.
