Due to the need of work, I have to leave my laptop on overnight with Ac power on. Will it damage the battery?

BTW, I just purchased it last month.

doesn't matter, if your battery doesn't work, or work shorter, you can change a new one, it is not expensive.

Laptop serves us, we don't need to serve laptop

Hi,

Battery maintenance for your computer is quite important. If you leave your batter unused, it does not matter. If you will use it, pls do not run it all the while night.

No matter the battery expensive or not, you should try your best to protect it! Because the battery is quite inportant to the laptop.
