Battery doesn't charge above 49%.

[Tudor97]

Hello,

I have an issue with the battery on my Pavilion 15t. The laptop was bought in 2017, so it's just one year old and shouldn't have problems with the battery. 

After I've made a battery test, the "Cycle count" in 150/1000. Also, my battery has 4 cells, but only 2 of them have actual voltage: Cell 1 and Cell 2 above 4400 mV and Cell 3, Cell 4 are both 0 mV. I think that's why the percentage of the battery don't get above ~50% (only 2 of 4 cells are working).  The laptop is out of warranty and I think it is not normal to be gone by now. 

What should I do? Should I change the battery?

I've attached a screenshot of the report.

(Sorry if there are any grammar mistakes, English is not my first language)

Thank you.

@Tudor97,

Thanks for reaching out to us on HP Support Forums! I see from your post that you are having issues with the battery not charging when turned on your HP laptop. Don't worry we'll work together to help you find a solution.

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

• Did this begin after any update like windows update, bios update or any other update?

• Have you tried with a different battery or charger if you could get hold of one? Could you try to check with a different wall outlet.

• Did you try to update the Bios?

For now please follow these steps.

• Uninstall the ACPI drivers from device manager for the battery.
•  Then test and calibrate the battery.
• Then change the power plan to the windows default plan.

Steps to uninstall the ACPI drivers

• Right-Click on start button> click device manager> Batteries>then select the s drivers and right-click on it and uninstall all battery drivers.
• Then restart the computer and check again.

 I would suggest here is to update the BIOS and the Chipset drivers to the latest version using the Official HP website for drivers and downloads: Click here to find it. 

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.

HP Notebook PCs - Testing and Calibrating the Battery (Windows 10)

HP Notebook PCs - Using and Testing the AC Power Adapter

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.

If the issue persists, I would suggest here is to try with a compatible charger and different wall outlet.

Could you please respond to this post with the details and with the results of the troubleshooting for further assistance.

Eagerly waiting for your response!

I hope you have a good day ahead,

And Feel free to ask your queries as this forum has some of the best people in the world available and ready to help.

@Jeet_singh,

Thanks for your response.

Regarding your requirements, I've tried to change the wall outlet and I got the same results. I didn't find another charger yet, but I will try it when I will get one. I tried to reinstall the ACPI drivers and test the battery, same results :).  My drivers are up-to-date, at least that's what  HP Support Assistant says. I also run the tests from HP PC Hardware Diagnostics for power and I've passed both battery and  AC Adapter tests. There were no failures.

I'm still thinking that the battery is the problem, more exactly these 2 of 4 cells, I think they are dead.

Looking forward for a response from you.

Thank you

@Tudor97,

Thank you for replying,

After reviewing your post thoroughly, I see that you have tried to follow the steps suggested and still seems to have an issue with the battery.

I would suggest you try to update the Bios and Chipset drivers on your PC and check if that helps. 

Alternatively, you can try with a different battery and AC adapter and check if that works.

Please note we're trying all possible things which should either help you in resolving the issue or to isolate what is the possible cause of the problem.

Please get back to us with the results, as this will help me in further assisting you.

Take care now and do have a fabulous week ahead. 🙂
