Acer 4250 schematic in PDF form for the ZQP project board, revision B, dated 0315 in the name, 952 KB. ZQP is a project code of the style Quanta uses, though the name gives no DA board number. The drawings let a technician trace power rails, charging and start-up circuits, and find components on a shorted line. Open it with a PDF viewer. Several ZQP schematic revisions exist, so make sure the revision printed on your PCB is B before trusting component values.
