net = self.parser.nets[comp.net_name] return [self.parser.components[r] for r in net.components if r != refdes]

Isolate the shorted rail. Inject a low voltage (typically 1V to avoid damaging chips) with a DC bench power supply. Pour a small amount of Isopropyl Alcohol (IPA) onto the board or use a thermal camera. The faulty component keeping the rail shorted will vaporize the alcohol or glow brightly under thermal imaging. Use the boardview to identify its part number, replace it, and test the board. Conclusion hp probook 4540s boardview
