Battery percentage is not increasing

[Ashik3]

 I have a HP 15-au627tx laptop and recently the charge on this laptop seems to be dying despite being plugged in. Initially it said that it was plugged in, not charging however now the battery is at 12% and it claims to be charging but the percentage does not go up. Is there anything I can do to fix this? Also, the charger works fine because i've tested it with a friend's laptop.

You can check the battery to some extent using Powershell built into Windows 10. as follows:
1) Press Windows key + X
2) Click Powershell in the menu
3) Type powercfg /batteryreport

This will generate a report and if you scroll down, you will see Design Capacity and Full Charge Capacity ratings. If the Full Charge Capacity is much less than 100% of the Design Capacity, it is faulty and needs to be replaced.

Thanks for replying, it shows design capacity as 41,149mWh and full charge capacity as 41,149mWh yet problem still persist

If the battery is not bad, that implies that the charging circuitry in the laptop is bad -- and that can not be repaired, as such.
