Schematic for the Lenovo Y510 laptop in PDF format, about 1.26 MB. The name gives no board number or revision, so read the ODM code printed on the motherboard and confirm it matches the drawing before trusting values. The document helps trace power rails from the adapter input, check the standby and main supply sequence, and identify components on a net that measures shorted. Any PDF reader opens it, and searching net names speeds up following signals between pages.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @schematicslaptop. Enginerys does not host this file.
