Hola amigos de badcaps, podria ayudarme?
tengo un equipo dell 3558 modelo de placa 1XVKN REV A00, tiene todos los voltajes los 3 y los 5 voltios, no hay cortos, recibe los 19v
preisono el boton y solo enciende el led 1 sola vez de color blanco y se apaga

Measure resistances on other inductors besides 3 and 5V. Some secondary voltage S3,S0 rail (memory for instance) might be shorted.

sorry for the delay, but I found that VCC_CORE is short, I'm afraid this signal comes from the processor, right?

What is the exact resistance on VCC_CORE?? You have processor soldered in this mb and very low resistance on VCORE area is normal.
