Odd thing about my dell laptop

[wipuhiku]

Hi Everybody.

I would like to ask something that my Dell laptop with Windows 10 Pro do. I change the battery on it because the battery that was in it only recharge up to 57%. So I bought a new battery which recharge up to 100%. But my Dell laptop (Dell Latitude E6420) has Windows 10 Pro 20H2 it acts a bit odd. Sometimes it start support charge the battery. When it does this it switch the computer off. Why does it do this? And is there any way to stop it from switching off it? Here comes odd thing too. I use the Linux Mint on it before I install Windows 10 Pro since Linux Mint stop working on it. When it use the Linux Mint it didn't switch off the computer when it support charged. Why does Windows 10 Pro do so?
