    Help with identifying a component

    Hello, I have a big problem with an HP computer with the epv51 la-g078p board, above the chip only the letters 8ieaqd appear and in BOARDVIEW it is identified as PU301, this component has shorted out and I am unable to find the replacement or the reference to be able to replace it, can someone help me? Thank you very much.

    Do you have the schematic for the board? Usually the board view files include the schematic in pdf format. If so, look for the part identifier and it will tell you what the part is and the value. From the PU designation, I would guess it's a pull up resistor on the power-up rail, but that's only a guess.

      What are the top markings on the ic? Post a clear picture of the ic
      It might be a SY8286BRAC QFN20 marked AWVxyz

          Clear as mud.

          What about BIExyz?

              I'm back to my old ways, after changing the component (SY8286B) sometimes it sends the 3.3v signal through pin 17 and when it feels like it stops feeding the equipment and turns off, can someone tell me what could be happening? The ENE was also changed and everything was reprogrammed, thanks
