Schematic covering the Lenovo Zhaoyang E390, E390A and E390M, a model family sold under Lenovo's Zhaoyang line, packaged as a 1.38 MB PDF. The name gives neither the board maker nor the board number or revision, so compare the title blocks with the markings on your PCB before trusting a specific page. Since one drawing covers three variants, check which options apply to your unit. Technicians use these pages to trace rails, follow signals and identify faulty parts.
