    HP EliteBook 845 G8 (need resistor values by EC chip please)

    Hello, I have an EliteBook 845 G8 motherboard sitting here. Customer knocked of 2 resistors by the EC chip. I cannot find schematics, board view or anything related to ID these 2 resistors.
    If someone has this board, could you please tell me the values of these 2 resistors?
    I hate to see this board be unusable due to something so minor....

    Thanks

    Windsor? Brother in crime? Bring it over...

    Meter in resistance mode. Measure the resistance from the resistor pads to the Winbond flash. Share the pin #.

      1.8 ohms from pin 8 to the right set of resistor pads (they are connected by a trace).
      7.10 M ohms on both pads on the left set of resistor pads (red to pin 8, black to resistor pads only).
      OL when testing the left set of resistor pads to each other.

      Thank you for your help.

        See attached. Pin # 8 on this device is the VCC (power) to the flash device @ 3v3.

        Meter in resistance mode. Touch your meter probes together. Do you read ~1R8 ohms? The same resistance should be measured from pin # 8 to the right side of the resistor pads.

        If yes, then we know that the missing resistors are pull-up resistors since the right side are mated to the VCC rail of 3v3.

        Now trace the left side pads of the missing resistors back to the flash IC PCB pads. Suspecting that you will find a continuity there as well. Post your updates.
