Laptop Battery Drains When Powered Off

HP Pavilion x360 Convertible
Microsoft Windows 10 (64-bit)

Ever since buying my HP Pavilion x360 Convertible (2-in-1) laptop over a month ago, the battery will lose significant power when it has been turned off for long periods of time. I will fully charge the laptop, turn off fully, and not use for a day or two, and upon turning my laptop back on, I will have lost almost 20% of my battery. However, if I charge fully and then use within the next day, it will say I have 100% battery. I have tried all the tips and tricks I have found online-- turning off the "quickstart" feature which allows things to start quicker upon booting up, turning off apps that automatically start upon booting up, etc. Battery diagnostic tests on the HP support assistant show no problems with the battery, and I am tired of charging my laptop only to lose 15% before I turn it on the next day. Is this a lemon computer, is this a problem with this laptop, or how can I fix this to actually get use of my whole battery?

Laptop Battery Drains When Powered Off

Hi! @Ryan_C1,


Please share the product number of your PC to assist you better.


I have checked the records there is a service advisory related to the issue you have mentioned.
Try updating BIOS and chipset drivers to the latest version using HP support assistant and check if it helps.


Refer this article to know more information about using HP support assistant.


Also, try the steps recommended below.


Step 01. Click on the Start Button
Step 02. Type "Device Manager" in the start search box & open the Device Manager
Step 03. Look for Batteries and expand it by click on the + symbol on the left
Step 04. Right Click on "Microsoft ACPI Compliant Control Method Battery" & uninstall
Note: This Battery driver will get reinstalled automatically when you restart the Notebook again
Step 05. Please Shutdown the Notebook
Step 06. Please remove the Battery and unplug the Power Adapter
Step 07. Press and Hold the Power Button for full 1 Minute
Step 08. Go ahead and put back the Battery and connect the Power Adapter
Step 09. Look for "Plugged In Charging" message on the Battery icon
After performing all the steps if you are facing the same issue still, please perform three more steps:
1. Run a Battery Check in HP Support Assistant[Install the Software if it's not available]
Note: Replace the Battery If Health Check Status shows Replace
2. Update the latest BIOS for your Notebook from HP Support Site
3. Please check your Notebook with a known good Power Adapter & Battery from a different Notebook 
Note: If a known good battery is also not charging we need to replace the system board.


Also, refer this document to understand more about calibrating batteries.


Let me know if this helps!

Have a great day! 🙂
