Battery suddenly drops when plugged

[katew10]

Hello.

I bought a brand new HP 440 G6 in the end of January. Since then every couple of weeks I notice something strange - battery suddenly goes from fully charged to low, even though it's plugged, and then it starts charging again. It doesn't happen gradually. It doesn't matter if I have the 80% threshold set or not, it happens no matter what. Please see attached battery reports from several months. I have all drivers and BIOS up to date. Why does it happen? Is it normal behaviour? How to fix it?

Thanks.

Anyone? I have a feeling that a $1000 laptop is not supposed to do so.

Consider:

Sudden drop in charge may indicate an issue with the ACPI Compliant Control driver.

Remove the driver from the Device Manager and reinstall.

Related to Microsoft ACPI Compliant Control

Example 1

Battery does not charge, possibly after Microsoft Updates (issue has been reported at least back to 2011)

Test system:  Pavilion Notebook

Contributed by Jeanydo

Symptoms:  Battery stops charging – no known issues with battery or charger – Windows 7 through 10 (at least)

Solution

Control Panel > icon view > Device Manager > Open Batteries > Right-Click “Microsoft ACPI-Compliant Control Method Battery" > Uninstall > tab Action > Check for hardware changes (reinstalls the driver)

Example 2

Symptoms:  Battery charges to 100% - notebook shuts down when battery dips to 50%.  Battery Diagnostics “cancel” (do not complete)

Test System:  HP Notebook 15-bs0xx

Solution (Paraphrased content)

• Unplug the charger
• Switch off the computer for 30 minutes, boot / start the computer, and log in
• Control Panel > icon view > Device Manager > Open Batteries > Right-Click “Microsoft ACPI-Compliant Control Method Battery" > Uninstall > Remove existing driver
• Shut down the computer
• If the battery is removable, remove the battery for one minute > Replace battery (Skip for non-removable battery)
• Start the computer and log in
• Control Panel > icon view > Device Manager > Open Batteries > Right-Click “Microsoft ACPI-Compliant Control Method Battery" > tab Action > Check for hardware changes (reinstall the driver)

Hello again. I did all the steps and unfortunately the issue appeared again. Could it be something to do with the battery itself? I still have warranty, but it's a bit tricky during these global circumstances.

Could be the battery, though this is not usually the case in a new computer.

I can understand the battery draining - even draining a bit faster than you would like might be in the boundaries of what is normal - sudden drops and other odd behavior not tied to how you are using the device are not expected.

• You can run some diagnostics, of course.   
• You can calibrate the battery. 
• You can make sure the system is being used properly (not sitting on your lap, running the recommended power settings, not gaming while on battery -- the usual common sense list).
• After you have tried the reasonable steps to cure the problem, it is time to contact Support.

Battery will not charge when system is warm to hot

If the “not charging” issue is (only) apparent when the system is running hot (or near that point), the battery and charge system are likely overheated as well – the charge system will resume operation when the computer cools down.  Short Version:  An overheated battery / computer / charging-system will not charge the battery – this is normal behavior.

Battery seems “stuck” in a particular charge setting         

The battery might be OK and just need calibration (balance / set).

The steps to check / calibrate / replace the battery are included in this document:

Document includes information and link for testing the hardware using HP PC Hardware Diagnostics (UEFI) (preferred method) and / or using the HP Support Assistant to test the battery.
