Ensure the voltage on the power button pin drops from 3.3V to 0V when pressed, and toggles the corresponding pin on the EC chip. Conclusion
A reliable way to verify a schematic is to cross-reference component values with known working boards. For example: lae791p rev 20 schematic diagram verified
Download the same schematic from multiple reputable sources and compare file hashes or content. Consistency across sources increases confidence in the document's authenticity. Ensure the voltage on the power button pin drops from 3
If you have the verified LA-E791P Rev 2.0 schematic file open on your screen, follow this troubleshooting flow chart: Troubleshooting Guide Using the Schematic 1
