Laptop battery discharges slightly when plugged in

[themusicman926]

I leave my laptop plugged in very often and I occasionally notice that the battery seems to slightly discharge. For example, my PC is always at 100% because I always have it plugged in but sometimes it goes down to 94% but it's still charging. Can someone please tell me if the PC is supposed to do this? I'm thinking it could possibly be just a way for the PC to make sure it doesn't over charge but I'm not sure. I have run some hardware diagnostics and it tells me my battery is fine.

Hi @themusicman926,

Thank you for visiting the HP Forums! A great place where you can find solutions for your issues with help from the community!

I understand you are having issues with battery not working as it's supposed to be on your HP notebook. Don't worry as I have a few suggestions which should help you resolve this issue.

The maximum capacity of the battery decreases over time and with use. Loss of battery capacity varies depending on the product configuration and usage, including but not limited to: product model, applications running, power management settings, and product features.

To provide you with an accurate solution, I'll need a few more details:

Did this happen after a recent software update or upgrade?

Have you tried to uninstall and reinstall the battery drivers from device manager?

Have you tried to update the Bios?

In the meantime, let's try these steps here:

Perform a Hard reset on the notebook: A power reset (or hard restart) clears all information from the computer's memory without erasing any personal data. Performing a power reset might fix conditions such as Windows not responding, a blank display, software freezing, keyboard stops responding, or other external devices locking up.

Next thing, please try these few steps to enhance battery life.

• Make sure that the Windows 10 power plan is set to Balanced  Performance to conserve battery power
• Consider which programs you are running; some programs, like graphics-intensive games, will deplete the battery faster
• .Reduce the convertible’s screen brightness to conserve battery power
• Remove peripherals like external hard drives from the convertible while they are not is use

Please follow the steps to uninstall Microsoft ACPI-Compliant Control from Device manager: 

Unplug the charge and use the laptop until the battery drains to 15%.

Turn off the laptop and turn it back on after 30mins.

Reinstalled Microsoft ACPI-Compliant Control Method Battery under device manager,

Restart the computer and the issue should be fixed.

Also, Go through them all and let me know what you have determined is causing the issue. The first document has the most relevant troubleshooting if your battery appears to be not charging.

I would suggest please update the Bios and Chipset drivers on your PC from our HP support website, using this link: http://hp.com/drivers Select the country and language. Enter the product# and follow the on-screen instructions.

Also, download and install HP support assistant on your PC. It should automatically download and install the latest updates and drivers for your PC.

Refer this link to know how to use HP support assistant.

Battery Does not Power Notebook or Hold a Charge

You can alternatively, try this link: HP Notebook PCs - Improving Battery Performance (Windows)

HP Notebook PCs - Testing and Calibrating the Battery (Windows 10) (Skip the steps if you have already performed).

Next thing, I would suggest here is to run the test on the battery from F2.(Click on Component test - Scroll down to Power)

Please remember to capture the failure ID for further assistance.

Please respond to this post with the result of your troubleshooting. I look forward to hearing from you.

Hello,

Thank you for replying to my question. Sorry it took me a while to respond.

This has been happening as long as I can remember. Probably since I bought the PC. I recently did a system recovery because of another problem I was having with my OS and the battery still occasionally discharged a bit even after a fresh recovery of my system. And I can not perform a hard reset as my battery isn't removeable.

Hi @themusicman926,

As I understand you have performed system recovery and still having issues with the battery getting discharged. In this scenario, I would suggest you try to uninstall and reinstall the battery drivers from device manager and then update the Bios.

Please follow the steps suggested in the previous post as this should definitely help in resolving the battery issue.

Let me know how it goes for further assistance!

Eagerly waiting for your response!

Regards,
