    Pin 2 ; ACP------ 20.3V
    Pin 1 ; ACN 20.3V

    I failed to add that there are 1.8V and 3.3V in EC, 1.8V PCH. That's why I think he could have deprogrammed the BIOS since the vital stresses are present and everything happened by installing a generic replacement upgrade. I don't think there is a problem with the charger itself.

    Next, locate charger IC PU2 = BQ24780SRUYR

    Carefully, measure the voltage to ground of the following pins:

    Pin 28; VCC
    Pin 4 ; ACDRV
    Pin 6 ; ACDET
    Pin 24 ; REGN
    Pin 2 ; ACP
    Pin 1 ; ACN
    Pin 28; VCC ---20V
    Pin 4 ; ACDRV ----26.1
    Pin 6 ; ACDET---- 2.6V
    Pin 24 ; REGN -----6.07V
    Pin 2 ; ACP------ 20.3V
    Pin 1 ; ACN 20.3V

    Thanks. ok I'll make those measurements and comment, I deleted the previous comment because I had made a mistake

    Thanks for commenting
    On both sides of the fuse there is 14.6V

    As I mentioned above, it also does not work with the 20V charger, with battery and without battery.

  • Lenovo V310-15ISK - It doesn't work after changing the battery

    Good guys. I changed the battery to a Lenovo V310-15ISK.

    The laptop worked perfectly, I changed the L15C4A02 battery because it didn't last very long.
    When I connected the new battery, the charging LED stopped lighting up and the one next to the charging pin also did not react when I pressed the power button. Minutes before changing the battery it worked perfectly and stopped working after putting the new one in. Even if you put the oroginal battery in or connect it without the battery, no LED lights up when you press the power button nor does it give an image, nor does the fan turn.

    Comparing the new battery with the original one I found this difference:

    Original battery 15C4A02
    Replacement battery: 15C3A01

    The seller told me that they are compatible for the V310-15ISK model, but now I am not sure

    Is it possible that this difference has caused it to stop working?

    It occurs to me that the BIOS may have been deprogrammed due to some incompatibility. I would like to know your opinions, advice or suggestions to solve the problem. Thank you so much
