Battery won't charge after a certain percentage

Pavilion 15
Microsoft Windows 10 (64-bit)

I have a HP Pavilion 15 and its still less than 2 years old,but recently my laptop's battery started behaving differently when the maximum percentage of charge started reducing from 100% to 80% to 60% and now has reached to 20% no matter how long I put the AC adapter on. This was a gradual process where I didn't realize the problem. Now it has reached to such a stage that the battery is stuck at 20% charging and there is no increase whatsoever.I even installed the updated BIOS and tried reinstalling the battery driver updates many a times but there's no improvement.

I have two questions :

1. How could I fix this?

2. If not,is my battery covered under a warranty so that I could redeem that?

Battery won't charge after a certain percentage

@NishkarshGautam
Thank you for posting on the HP Support Community.

  • Did this happen after a recent window or software update?
  • Did you try another charger?
  • Does the notebook shut down immediately (right after you unplug the charger)?
  • Do you get any error message on your notebook (Such as Plugged in, not charging, etc.)?

While you respond to that, let's try these steps: 

Hard Reset: Follow steps from the link: https://hp.care/2GnkMa8.

BIOS default: 

  1. Turn off the computer and wait five seconds.
  2. Press the Power button to start the computer and repeatedly press the F10 key to enter the BIOS setup menu.
  3. On the BIOS Setup screen, press F9 to select and load the BIOS Setup Default settings.
  4. Press F10 to Save and Exit.
  5. Use the arrow keys to select Yes, then press Enter when asked Exit Saving Changes?
  6. Follow the prompts to restart your computer. If the issue persists, follow next steps.

Run hardware diagnostics test on battery and Charger:

Use the following steps to open the Component Tests menu.

  1. Hold the power button for at least five seconds to turn off the computer.
  2. Turn on the computer and immediately press Esc repeatedly, about once every second. When the menu appears, press the F2 key.
  3. On the main menu, click Component Tests.
  4. The Component Tests menu displays. Your Component Tests menu might be different, depending on the components installed on your computer.
  5. To run both tests simultaneously, in the Component Tests menu, click Power Source, and then click Run once. Each component can also be tested individually.

AC Adapter Test:

The AC Adapter test provides an interactive test to determine if the AC power adapter is functioning properly. A good battery is required for this test. Before running the AC Adapter Test, HP recommends verifying that your computer can receive power by connecting a known working AC adapter.

Follow these steps to perform the AC Adapter Test.

  • In the Component Tests menu, click Power, and then click an AC Adapter Test.
  • Click Run once.
  • The AC Adapter Test begins.
  • When the test is complete, the results are displayed on the screen.

Battery Test:

Follow these steps to perform the Battery Test:

  1. In the Component Tests menu, click Power, and then click Battery.
  2. Click Run once. The Battery Test begins.
  3. When the battery test is complete, the results are displayed on the screen. For additional battery information, click Battery Details.

If the test passes, continue with these steps:

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 possible, try an alternate charger.

 

Hope this helps! Keep me posted for further assistance.

  Thank you for your reply. I'll like to add that,

  •  No, this did not happen after any Windows update I installed
  • I did use a different charger but the problem still persists
  • After I unplug my charger, laptop displays  low battery and then after a while, it shuts down automatically due to no battery backup

 

I did carry out all the remedial steps you mentioned and everything responded fine but the battery test.

It reported a failure. I don't know whether this test is reliable or not and if I should take it seriously.

 

Also, I read on an HP Community portal about warranty terms and conditions where it mentions that Long-life,

non-removable batteries are covered under a warranty of 3 years and mine is one too. So is my battery under a warranty period as of now?

I'll provide the link for your reference-

I've already contacted HP customer support twice but they have never followed up from their side.

Also, I would like to know about the warranty terms and conditions for my battery as I asked you before. The link I provided had something mentioned about HP notebook, Long-Life non-removable battery warranty. I just want you to check and tell me whether that is applicable to my laptop or not
