Hi @mhamrick1956,

Welcome to HP Support Community. This is a great place to post questions and find answers.
Thank you for posting your query, I will be glad to help you.

I see that you are facing battery issues with your HP ENVY Notebook - 17-S010nr (ENERGY STAR).

Please follow the steps listed below to update the drivers from device manager:

1) In the Windows search box on the desktop, type “Device Manager” and then click on it.
2) Expand “Batteries”. 
3) Right-click the "Microsoft ACPI-Compliant Control Method Battery" that is listed there. 
4) Click on “Uninstall”. 
5) At the prompt put a check in the box to remove the current driver 
6) Restart the computer. 
7) When the computer comes back up it should automatically find the driver. 
😎 Go to Device Manager. 
9) Expand Batteries. 
10) Right-click the "Microsoft ACPI-Compliant Control Method Battery" that is listed there and click on update drivers.
11) Click "Search automatically for updated driver software" 
Do the same thing with Microsoft ACPI-Compliant Embedded Controller.

I did what you said . And it does the same thing ? when i run hp support assistant and do a battery check  it says charged 1005 Primary battery : No battery  A battery was not detected . If a battery is installed re-insert battery and ac adapter  to retest battery . I did that also  still says the same thing battery not detected . Crazy !

Hi @mhamrick1956,

This could be a hardware issue with the unit and may need repair. 

I suggest that you contact HP Service Center in your location from this web link
Note: Select your country from the dropdown,  enter the city or postal code, select the product, change the radius, and click on search to locate the nearest HP Service center near your location.

Hope this helps.
Take care and have a good day.
