Battery percent stuck

[ashmint]

My HP laptop battery is stuck at 12 percent right now. When connected to the adaptor it says charging but I tried charging it for about an hour now and it's still at 12 percent.

I also tried to discharge it by playing some YouTube videos with max brightness but the percent is still stuck a 12 percent even after 4 hours now.

It's not an old battery, around 7 months now. I tried running the hp diagnostic tests and everything says it's okay. Any suggestions on what I could do. I couldn't see a calibrate option inside the UEFI diagnostic tool. Should I try draining the battery and then try to charge it. Please help.

Forgot to mention that the battery light is white and blinking when it's discharging.

Also the cell voltage and current of the battery is the same after running the tests at different intervals. Looks like the battery info shown is faulty.
