    Power issues with HP pavillion 15 eh1815nd

    Hello,

    I have some issues with my HP pavillion 15 eh1815nd.
    It doesn't wanna power on anymore, when i click the start button it briefly turns white, then the light goes off again.
    The charge light is indicating that it's charging when i plug it in.

    I did some tests accross the board, and found 2 (coils?) near the CPU, one of the small (chips?) next to the bottom coil seems to get unusually hot, and the coil shows quite a lower resistance then the coil above.
    Most/all capacitors next to, and below the bottom coil seem to be connected to ground on both sides, this is not the case for the top coil.

    Test results:

    Top coil, ground to coil > 120ohms

    Bottom coil, ground to coil > 41.8ohms

    I will include some pictures of the affected presumebly coils, and surrounding area.

    Would anyone be able to offer me a hand? i am still quite new to this stuff, so please correct any mistakes i might have made explaining/testing this issue.

    The resistance to GND readings on coil is meaningless if we dont know what the coil stands for.
    Link schematic/BV if posted on forum and share mb part number.

      Hello, thanks for the reply!
      Sorry about that, i am still learning.

      The MB part number is DAG7HAMB8F0 REV F

      (i will also include the part number and the board in whole as pictures)

        I did some searching, and found that the little chip next to those inductors/coils is TPS51486RJER component labeled PU8700, so a power managing for the memory and the CPU? if that fails, would it cause the surrounding area to short out?
