Battery percentage stuck at 99%

[FFmpegTS]

Hello! For some reason, the percentage of the laptop's charge stuck at 99%. And when using a laptop on battery power, the percentage does not change.

Updated bios. Performed battery diagnostics using HP PC Hardware Diagnostics Windows. Everything is fine with the battery. The laptop is new. Reset bios settings. Did not help. I even reinstalled the operating system, but it still did not help! Booted into WinPE, still the same 99% when running on battery power.

Can you tell me what can be done to fix the problem?

Hi@FFmpegTS,

Welcome to the HP Support Community! I'd like to help!

I see you are experiencing Battery issues with the HP Pavilion 15.6 Inch Laptop PC.  

I have a few recommendations 

• It is designed to help optimize battery life by mitigating the exposure of the notebook battery to key factors, such as high state-of-charge, that can accelerate battery swelling and chemical aging over time.
• Overheating a battery will shorten its life, so some computers stop charging at 99%.
• For Testing and Calibrating the Battery please click this link

Hope this helps! Keep me posted.

Yes, I tried to calibrate the battery according to the instructions https://support.hp.com/in-en/document/c04700771

Did not receive calibration.

The laptop did not overheat, it charged correctly. 

This laptop does not heat up at all in everyday tasks.

Tell me how you can reset the battery calibration? Maybe there is a tool?

HP Hardware Diagnostics and HP Support Assistant I have tried. Battery condition is ok.
