Battery drops 50% when laptop is turned off

HP Recommended
HP Envy 13 ah0021nb
Microsoft Windows 10 (64-bit)

Lately my battery has been draining just over the course of 24 hours from 100 to about 50% without me using the device. I have tried just closing my laptop and leaving it in stand-by mode for a day, but I have also shut it off completely, but the result remains the same. Is there something I can do?

 

I was thinking about ordering a new battery on the HP parts store but they don't sell what I need...

Hi@HannesDossche, Welcome to the HP Support Community!

 

While you respond to that, I recommend you to perform the following steps to isolate the issue and arrive at a fix: 

NOTE: You may skip any steps that have been performed by you already.

  • Power off the laptop.
  • Remove the battery out. If the battery is integrated and does not have a latch to release it then leave the battery inside the laptop.
  • Disconnected AC adapter from the laptop.
  • Press and hold the power button for 15 seconds.
  • Reconnect the battery and plug the AC adapter.
  • Power ON the laptop.

Now let us uninstall the battery drivers and reinstall them. The following steps will help:

  • Open the device manager. 
  • Expand "Batteries". Right-click on the ACPI battery drivers and select uninstall. If there are multiple entries of the ACPI battery drivers then uninstall them all.
  • Close the device manager. Restart the laptop.
  • The Windows operating system will reinstall the battery drivers while restarting. 

It is a good idea to download and run a BIOS update for your laptop via this link. The charger must be connected until the BIOS update is complete to avoid any power interruptions due to the battery draining out. 

 

Post a successful BIOS update,  you may check if the battery charges fully. If not then please perform the steps as described in detail in this HP document. These steps help in testing and calibrating the battery. 

NOTE: Please skip the steps mentioned in "Test and calibrate the battery using HP Support Assistant".

 

I sincerely hope this fixes the issue. Keep me posted. 

 

Hope this helps! Keep me posted.
