Hi,

Try and uninstall and reinstall the latest graphics card driver from NVIDIA support site first and see if this will fix the issue.
- Uninstall the graphics card driver from Device Manager and in Programs and Features as well since it should have something related to NVIDIA in there as well.
- Once uninstalled download and install the latest driver from NVIDIA support site.
- Here's the link: nvidia.com/download/index.aspx
- Use the Auto Detect feature so they could give you the latest and accurate driver for your graphics card.
- Lastly reboot it once the latest driver has been installed.

Lastly, to uninstall and reinstall the ACPI driver in Device Manager as well that driver controls the charging and detection of your laptop battery.
