    Which Smd component to replace - DAG3JBMB8D0

    Hello first of all, data to take into account:

    Motherboard: DAG3JBMB8D0 REV: D
    Computer: HP Pavilion Gaming Laptop - 16-a0006tx
    Diagram/schematic/boardview: I can't find them yet.
    Problem: Computer turns on and shuts down immediately.

    Well, I'm not an expert nor a technician, I just repair things for hobby, some time ago I got a motherboard with its power cable and button.
    I assume that the board had been intervened by a technician, they reprogrammed the E.C. and main bios.
    I made measurements until I got to the E.C. bios that did not receive voltage, I came to the conclusion that it had short components after a visual check millimeter by millimeter, I found that it had 3 missing components.
    this is the best image I got of this plate



    I rebuilt the track in a sector where one component was missing, the other 2 missing components I assumed that I could place the twisted component and it would make the same contact.





    Here come the problems, as I am new to this subject I do not know what components go in those sectors, by the size could be a capacitor or a resistor, I'm just guessing since I have no idea. if someone could give me some help on what component goes in the right place I would appreciate it very much.
    In the images I put numbers and mark the area where the components are missing, I also made measurements ala track where the components were missing as seen in this image:





    thank you very much any kind of help is welcome.

      Hi, budiex! I have such a fee at work and on Monday I can take a photo with measurements of the parameters of the elements in the right place. There are no elements in the IT5570 binding on my board. I hope for reciprocal help in my problem.

        Hi, budiex! I took a photo of my board and measured the parameters of the elements. Please help me with my problem. Next to IT5570 there are empty areas after the board is filled in. Apparently, the elements in this place have rotted.
