Windows not showing correct battery charge


New Member
When the charger is plugged in the battery charge display is stuck at 8% for several minutes. Other times when the battery is fully charged and the charger is unplugged the battery display remains stuck at 100% for several minutes. The laptop also shuts down due to a low battery. Before it shuts down the battery display may show a charge above 20%. After I plug in the charger and turn the laptop on the battery display shows a 4% charge.
I have tried calibrating the battery, reinstalling the Microsoft ACPI-Compliant Control Method Battery driver and updating windows. Nothing has worked.
I have a lenovo X131e that is about 6 years old. The battery is new however. Below are some details about the battery:
