Battery Charges Slowly After 90%

[sigmasixleads]

The problem I have after BIOS update(F.38) is that the battery charges very slowly after around 90%. Before BIOS update, the whole process of charging from 0% to %100 was taking 90 minutes, but now it takes 90 minutes from %0 to %90 and the left %10 takes almost two hours nonsensically. Any idea?

Greetings @sigmasixleads, 

Thanks for the post. 

I understand that your computer is taking a long time to charge, is that right?

Not to worry, I will be glad to assist you. 

Have you run a diagnostics on your computer?

Have you tried to update all the drivers using HP Support Assistant?

Are you using the same power adapter that was bundled with your computer?

Please run HP Support Assistant to make sure chipset and other drivers are updated. 

Refer to this HP Article for assistance in using HPSA. 

Once all the drivers are updated, download and install UEFI Diagnostics on your computer from this link. 

After installing UEFI, please shut down your computer. 

Wait for a minute. 

Turn the computer On and keep tapping F2 repeatedly on startup to enter system diagnostics. 

Select the component test in system diagnostics and run a battery test on your computer. 

If the battery test fails, please replace the battery or contact our phone support to check on any service options available for your computer. 

If the test passes, please restart your computer. 

Open device manager by doing a right-click on the Windows button. 

Uninstall the battery controllers (you might see multiple of them listed.) 

Delete the driver when prompted during uninstallation of the driver. 

Restart the computer couple times to refresh the driver and check the performance of the battery. 

If the issue persists, refer to this HP Article and perform a calibration on the battery. 

To the best of my knowledge, BIOS update will not reduce the time taken by the battery to charge. 

However, you would like to rollback the BIOS on your computer, you can do so by booting the computer while holding down Win + B keys on the keyboard. 

Refer to this HP Article for assistance. 

Let me know if this helped.
