    Good morning.

    After reading these last few days a lot of posts about my problem (when I was updating the BIOS of my DELL XPS 12 laptop from the Dell website and when I was at 30% it stopped doing anything and died) I think the only solution is to desolder the chip the bios and put a new chip with the BIOS. I have found a store here in my country. That you send them the disassembled motherboard and they change the bios chip with the latest BIOS from the manufacturer and I think I'm going to do it like this. My question is: In my model you only have to change the BIOS chip to be able to start the computer or is there more than one CHIP because I have read that some models have two chips (BIOS and EC) and that you have to change them both? .

    Thank you very much for your help.

    "It is worth remembering that you must always update in chronological order, ie all URGENT updates in chronological order. This is a mandatory renewal order.
    You can skip the so-called Recommended Updates. They not mandatory."

    This I think I did wrong. Because you get out of the bios that had the last one without going through the intermediate ones.
