I think your "notta" should be "nada"...
Anyway, I don't know what you switched, but it seems like you did not switch off the eMMC. But don't worry about that right now, you don't need to switch it off. And your SD card is not imaged correctly. Your PBP *does* power up when you have the SD card in, but nothing is running to turn the power light on. You need a bootable image specific for SD card; the wiki has links for valid images. Then you need to write it to the card correctly. I suggest hopefully the wiki tells how to do this because the way I do it, with command "dd" is probably not the way you will. If that is how you are doing it, just make sure to write to the card itself, not a partition.
The card must have first, boot code, in our case U-Boot, next a FAT partition called for U-boot to read, next usually whatever your operating system needs. This is important. If those first two things are not at the very start of the card, and not aligned properly, the PBP will not boot, and again, the power light will not be turned on, because it is only turned on by software.
