HP ProBook 4540s Repair Help: Learn How to Fix It Yourself. - iFixit

Often a SMSC MEC series chip, responsible for power sequencing.

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
