Schematic in PDF form, packed in RAR, for the Wistron board 17823-1N (project 17823). Wistron uses numeric project codes like this one, and the full number appears on the mainboard silkscreen. It is associated with Lenovo ideapad 720S laptops. The schematic helps trace power rails, charging circuits and signal paths when fixing no-power, no-charge or no-display faults. Open it in any PDF reader after unpacking, and make sure the PCB number and revision match your board before relying on component values.
