    Who can help to tell the resistor value please?

    It looks 01.

    see the pic yellow circle below.
    Thanks

        You might have better luck posting the board number or model number, What is it's resistance when checked with a meter?
        It could be a D01R3721F-GP-U

          That looks to be Source resistor for the MOSFET PU4402 which is connected in series with MOSFET PU4201 as half-bridge set up. I expect that resistor to be <1 Ohm.
          Why do you believe that resistor is bad?
          What is this board for?

            Thanks

            Its a 10 milli ohms resistor

              Looks like a laptop?
              Current sense resistor for AC or battery power circuit it looks like.

              What is the problem with the laptop?

                Hallo
                i have a Yoga L380 LKL-1 Mainboard
                there the PR4402 is only 0,6 Ohm instead the 1,0 Ohm that results in Slow charge and Fault messages regarding the charger

                According Schem its a D01R3721F-GP-U

                because you know that resistor .... do you know where i can get it ?
                Prefer Europe but i can order world wide

                Thank you

                  Sorry all posted Values are wrong

                  Marking R010
                  acc calculator it should be a 0,01 Ohm

                  With this low resistance value, the measurement cable must also be taken into account.
                  Unfortunately, I don't have a milliohm meter at the moment and all other measuring devices are too imprecise.
                  Best way is to change it to be shure
