    Fitted new battery tp HP G56 laptop and it is fully charged. However as soon as I disconnect the power supply, the laptop turns off. Anyone got a solution?

    Laptop own power cable not recognized


    I haven't tried because the jack is different size, too thick. When laptop is turned off, the "bad" power cable does power original laptop - I see the led light gives the right sign. However, when I turn on the laptop, I do get the runtime error and dimmed screen as if I disconnected the power cable. I must say the problem isn't persisting any more, meaning, if I unplug the cable and plug it back a few times, the laptop works normally for longer periods. Thanks!

    Does the other laptop work with the bad power cable? If not, then your power adapter/cable went bad.

    windows 10 battery plugged in not charging (acer v11 touch)

    Hello,



    We appreciate that you already performed troubleshooting. On the other hand, we will be providing steps that seems to be the same with what you have done but with tweaks.



    If ever you encounter case wherein the laptop is plugged in but is not charging, we suggest that you try the following:

    • Disconnect the laptop’s power cable from the outlet/power source and laptop.
    • Turn off the laptop.
    • Remove the battery.
    • Reconnect the laptop’s power cable to the laptop then to the outlet/power source.
    • Power on the laptop.
    • Uninstall device of Microsoft ACPI-Compliant Control Method Battery
    • Turn off the laptop and then disconnect the power cable.
    • Insert the battery.
    • Reconnect the power cable.
    • Power on the laptop. Windows would then reinstall driver automatically.


    In case that the troubleshooting steps above didn’t help, our next step is update the driver if there is available update. You just have to go back to
    Device Manager > Batteries > Right click on Microsoft ACPI-Compliant Control Method Battery > Update Driver Software.



    Let me know if this works for you.
