Battery issue after bios update

[DrRicky31]

I recently updated windows 10 and BIOS on my laptop, at the end the battery that the system reported was about half of the real capacity. This means that when the battery is at about 50% the computer shuts down and when it restarts the battery is at 0%. analyzing the mWh reported at restart are less than half of those actually available. I wanted to know if it was possible to rollback the bios and go back to the previous version or if it was possible to fix it in other ways. I attach details on the bios currently installed: BIOS: F.21-07 / 22/2021

 Hi@DrRicky31,

Welcome to the HP Support Community!

Don't worry I'll try to help you out.

unfortunately, BIOS rollback is not an option.

We understand the issue with the battery not charging, it is due to a BIOS update might its battery will be faulty.

Let's try this:

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.

Hope this helps! Keep me posted for further assistance.

Unfortunately it is not a hardware problem, the diagnostics did not bring any negative results, but in fact the battery goes from 34.000mWh maximum to about 12.000. Is there any software update available?

Hi@DrRicky31,

`We have done the basic troubleshooting as per the document and the notebook needs to be checked taking remote access so that get to know it's a hardware or software issue.

I'd suggest you contact HP in your region regarding the service options for your computer or HP Chat Support Team.
