Prende no da video

@josemajoaltamar your questions seems to lose something in translation. Are you saying you do have video ro you do not have video. If you do not see anything on your display, but your Dell has turned on, you do want to connect an external monitor and see if that displays something. If you don't see anything, then it is possible that your Dell does not find the OS. I have had this happen before because of a failed HDD. Let us know what an external monitor does show you.

Translation

@josemajoaltamar tus preguntas parecen perder algo en la traducción. Estas diciendo que si tienes video ro que no tienes video. Si no ves nada en tu pantalla, pero tu Dell se ha encendido, es posible que quieras conectar un monitor externo y ver si muestra algo. Si usted no ve nada, entonces es posible que su Dell no encuentra el sistema operativo. A mi me ha pasado antes debido a un disco duro defectuoso. Háganos saber lo que un monitor externo le muestra.
