Working on the "Top" side requires precision. The BKM33BTV2 uses lead-free solder with a high melting point.
Always flash the BIOS to the latest version after repairing the hardware. The V2 boards have a specific EC firmware update that changes the fan curve to blow air across the Top PCB rather than away from it, drastically improving the lifespan of your repair.

Switch your multimeter to continuity mode. Probe the large inductors (marked "R22" or "R15") next to the CPU. If they beep against ground, you have a short. Working on the "Top" side requires precision
Use a thermal camera or isopropyl alcohol (spread on the caps) and inject 1V at 3A into the shorted rail. The faulty capacitor (usually a 330µF tantalum or MLCC) will heat up. The V2 boards have a specific EC firmware
