    Advice for the person that have RT809F

    when you read a chip that isn`t supported choose a different chip with 512 capacity
    use W25Q512NW that support 1.8v ...no 1.8V adapter is needed ....ignore check-ID

    Thank you SMDFlea for your help

          Dell Latitude 5350 Ultra 7 Motherboard
          by Julian Bailey
          Hi

          I have a Dell Latitude 5350 Ultra 7 Motherboard I am trying to repair that has a blown chip.

          The chip is marked as eHOLH similar to the one I have pictured.

          Any ideas what it does and what the pin outs are as 3 tracks have gone and need to find out what / where they went / did etc.

          Dell PN of the motherboard is 08DCGW.




          Below is the area I am trying to repair:



          Does anyone have a picture of this motherboard in this area they could take and upload?

          Cheers...
