Callibration process how i carried-
First of all i charged the battery to 100% and then unplug the adapter from laptop, after that i used the laptop until it got switched off and after it was off, i kept the power button of laptop pressed for drainage of left battery power and then i removed the battery from laptop and again pressed the power button for few seconds. After 5 minutes i plugged the charger and i switch on the laptop.


After this message i callibrated again to resolve the problem but still problem resisted .
Welcome to the forum

First we need to check if the battery and the laptop work properly.

To do that, you will need to get a different battery (from a friend, or a colleague, or at a service center) and plug it to the laptop.
If it works fine then your old battery is faulty. Make sure that the battery works with another laptop before testing it.

Also, please check your adapter, a faulty one can damage the battery.

Have you chosen a power plan for your laptop? You can do so from the Control Panel.

A google search reveals that some HP laptops were affected by a False alarm by Windows. Here is a link to the page where I read about it:
