Z40-70 Won't charge. Battery stops at 6%. Unauthorized battery message

2016-10-21, 19:48 PM

Hi, I barely use my new Lenovo Z40-70 and now I am having an issue with the battery. It shows that the battery is not charging and get stock in 6%. The laptop only works with the power adapter. I tried rebooting the system, removing the battery, pressing the power button for 40 seconds, I uninstalled the Power Manager, I uninstalled and Installed the Microsoft ACPI-Compliant Control Method Battery  and installed again and nothing worked. Last thing I did was updating the battery firmware and after that, I am getting a message telling me that I have an unauthorized battery.....and my issue continues.........please help me :-(

If its an original Lenovo battery you're going to have to call tech support. I doubt anyone run into that issue here.
