HP Envy Laptop Battery not charging after Windows 10 installation

Hi,

Thank you for posting on Microsoft Communities.

I suggest you to un-install and re-install battery drivers from Device manager and check. Follow the steps:

• Press Windows Key + X.
• Click on Device Manager.
• Expand Batteries and right click on Batteries ACPI and click on Un-install.
• Restart the computer and check.

If the issue persist, I suggest you to visit HP Envy website and check whether HP has released any firmware updates for Windows 10. If so, please go ahead and install them and check with the issue.
