As I understand the laptop's battery is discharging while it's in a shutdown state and you need assistance in resolving this concern, I have a few suggestions for you,


Let's start with updating the BIOS and the Chipset drivers to the latest version using the Official HP website for drivers and downloads: Click here to find it.


You will need to Understand Lithium-Ion and Smart Battery Technology: Click here for details


Resetting the ACPI battery driver may take care of this. There will be a hard reset mixed in as well, so the two methods combined typically help a lot with battery issues.


1. Go to Start, search for Device Manager, and open this result.

2. Expand batteries.

3. Right-click on the ACPI option (usually the 2nd option) and select delete or uninstall. Follow the prompts.

4. Shut down the computer.

5. Disconnect the charger.

6. Remove the battery.

7. Hold down the power button for 1 minute.

8. Insert the battery only.

9. Attempt to turn the battery on.


If this had an impact, it should behave differently.

If not, Press the power button and then tap the F2 key to invoke the startup menu.


Run a battery test using F2 (during restart), if the test failed: 

Check with an alternate battery. 


If the test passes and yet, the issue persists: 

Within BIOS there's an option that provides energy to the Type-C USB port even when the notebook is turned off. 


Hence, I recommend you disable this feature to fix the battery drain.  

Please find the details listed below: 


  • Press the power button and then tap the F2 key to invoke the start-up menu. 

  • Choose and click on the F10 key to invoke the BIOS. 

  • Use the System Configuration tab. Disable USB Charging  and press the F10 key to save the changes and boot into Windows. 

Keep me posted,
