This 112 KB PDF in the schematic section is named 20ETF-S-HV. The name lists no laptop model, board number or revision, only a part-style code with S and HV suffixes. HV often suggests a higher-voltage variant, but treat that as unconfirmed until you have read the document. It opens in any PDF reader. Technicians use such references to check ratings and package details before fitting a replacement. Confirm that the marking on the installed component matches this exact variant.
