When I tried to calibrate it, I turn in off, and connect to AC, but LED indicator is changing from orange(charging) to white(charged) by minut. When I play video games, my fps drops when laptop is on battery. So when i play, my fps goes up and down because my laptop is switching from AC to battery. Now I took out battery and it's working just fine, only problem is that BIOS settings restore to default every single time when I turn on laptop. So, problem is definitely with battery on some electronic part, who is in charge on switching from charging to AC.

I did it. All test passed. No error or messages. But the interesting thing is that my laptop is now not switching from AC to battery, but I am sure that tomorrow, the problem will come back. I think I have a problem with some electronic part(like some controller, if HP laptops have something like that), or my battery is faulty. When the problem started, I changed battery, and the problem was still there, so maybe is not a faulty battery.
