LG P420 laptop schematic designed by Quanta, project QLC, motherboard DA0QLCMB8D0 at revision D. At 3.94 MB the PDF is a detailed set of circuit pages, handy for tracing power rails, charger and enable signals, and checking component values while chasing a short or a no-boot fault. Quanta built this board for LG, and its DA0 numbering carries the QLC project code. Confirm the number and revision D printed on your PCB before relying on these drawings, since other revisions may use different parts.
