Thank you! The machine now turns on, but does not show a picture, after a long wait it turns on and off every few seconds.

Hi! Unfortunately I don't know how to edit the bios, so I'm asking for your help, I've already tried several files, which have only worked until the dell logo. Is there any hope for the machine to work?

Esta BIOS muestra la imagen, pero el teclado no funciona y no reconoce el disco duro. Ya ingresé la etiqueta de servicio manualmente y pasó lo mismo.
