Technicians use a multimeter in to measure the voltage drop on the PP_VAR_USB_RVP line. A reading too close to zero (e.g., below 0.050V) indicates a short circuit. 2. Identifying the Shorted Component pp-var-usb-rvp

By validating the input through the PP_VAR_USB_RVP stage, the logic board ensures that current flows only one way and stabilizes within safe parameter windows before moving downstream. ppvar_sys: ppvar-sys compatible = "regulator-fixed"
