i have been using this laptop for 2 years i get it from my friend .

from start it always charges battery upto 56 percent.

and i thought that there is problem in the battery cell and in few months battery backup becomes very short.

Yesterday i bought a new battery for my laptop but it is giving me the same problem which i had with my previous battery.

So this is not battery problem.

Things i have tried

1)Removing battery and uninstalling windows ac adaptor from Device manager.

2)Removing both battery and power Adaptor and pushing the power button for 20 sec if there is any residuel current.

Nothing has worked for me so far.

I would be thankful for your guidance.

Thank you
(I'm running windows 10 X64)
