    lenovo ideapad 720S-13IKB need dump

    Hello everybody,

    Trying to find bios dump for this lenovo laptop, motherboard code DS321 NM-B331 rev 1.0.
    It only powers on nothing more.
    I wanted to start from bios reprogramming first.

    It has 2 chips (attached both dumps), if somebody can check-correct those or attach working dumps will be perfect!

    original.rar

    Thanks in advance

              Your file seems to be ok but still extracted main bios(8MB) from lenovo update. Try it.

                  Thanks everybody for the help.
                  @mcplslg123 tired your file but I have the same result.
                  Laptop powers on only, no picture Vcore is there maybe problem on ram chips or cpu.

                  I hope the dumps might help somebody.

                      That is what i doubted as your dump seemed fine to me. Check DRAMRST on pin30 of ram slot. Should be 1.3V if PC3-L memory.

                          Well after searching around I found a shorted cap near usb C charging connector.
                          The strange thing was that laptop was showing signs of life.
                          So I can confirm both my dumps and yours are OK if somebody needs those.

                          Thanks for the help
