How to solve the "Calibrate (20)" error in battery test in HP Support Assistant?

[Sruj]

Hi, I am using a HP Omen 15. I just replaced my battery last month and when I checked the battery test, I got a message saying that the battery needs to be calibrated and the error name was "Calibrate (20)". It asked be to calibrate by running the battery check by plugging in for 3 more hours after it is fully charged. I calibrated it as it said and even their the error appears.

Please help me to solve this.

Thank you for posting on HP Support Community.
 

Don't worry as I'll be glad to help, I have a few troubleshooting steps we could try to fix the issue:  

Manually calibrating the battery requires four steps: fully charge the battery, discharge or drain the battery, recharge the battery, and then run the battery test. Calibrating the battery improves the accuracy of the battery gauge software so that it more accurately displays the current level of charge. The following instructions work with most battery types.
 

Step 1: Charge the battery

Use the power cord to charge the battery to a full charge.

1. Plug in the power cord.

2. Charge the battery to a full charge, 99% to 100%. To check the battery charge, mouse over the battery icon in the system tray on the Desktop.

3. When the battery is fully charged, proceed to the next step.

Step 2: Discharge the battery

After the battery fully charges, use HP PC Hardware Diagnostics to discharge the battery.

1. Unplug the power cord.

2. Press and hold the Power button for at least five seconds to turn off the computer.

3. Turn on the computer and immediately press the F2 key repeatedly, about once every second until the HP PC Hardware Diagnostics UEFI menu displays.

4. Click Component Tests in the main menu.

   NOTE: The purpose is to drain or discharge the battery, not get the results of the test. The battery discharges and the computer turns off before the test results display.

5. In the list of Component Tests, click Memory.

6. Click Extensive Test.

7. Click Loop until error to start the test. Let the test continue until the battery is completely discharged and the computer shuts down.

   NOTE: This test only discharges the battery and does not impact the memory.

Step 3: Recharge the battery

Recharge the battery fully before you calibrate the battery.

NOTE: If you run the HP Battery Check before the battery charges fully, you might get a false battery failure result.

1. Plug in the power cord to charge the battery.

2. Charge the battery to a full charge, 99% to 100%. To make sure the computer reaches a full charge, keep the computer attached to the power cord for at least 3 hours.

   NOTE: The battery continues to charge with the computer on or off.

3. Check the battery charge. Turn on the computer and start Windows normally. On the desktop mouse over the battery icon in the system tray to view the battery charge percentage. Make sure the battery charge percentage is 99% or 100%.
   
   NOTE: If you plug in your power cord and immediately run the HP Battery Check, you might get a false failure showing the battery is bad. If the battery is in a low-charge state (at less than 3%) you might also get a false reading.

Hope this helps! Keep me posted for further assistance.

I have tried these steps several times ,  following to the letter,  and I still get the same results.  The battery in my unit is factory sealed, so I cannot swap it out , but will have to get it serviced.  When I search for replacement parts, I cannot find a replacement battery and most other items in the parts inventory are out of stock with backlogged orders.

If you have followed these steps repeatedly, and still found that the battery is requiring calibration, then the battery is defective and will require replacement... This is normal, as sometimes batteries my prematurely wear out, with very low charge cycles as the battery is made up of ephemeral materials (meaning that the Lithium Ions within the battery may loose polarity, and/or will be far less effective if exposed to higher temperature, short cycles from charging from 99% to 100% repeatedly in a short period of time.)
