Could anyone tell me how a battery in a laptop is recharged. Does it happen when laptop is connected to mains electricity? Thanks in advnace

Seems like a really odd question. I assume theres some reason behind the question.

Yes of course it charges when plugged into the mains, how else would it charge?

If its in use at the time then it uses some power to run the laptop and some to charge the battery, when the battery is fully charged the charging cycle stops and it just uses the mains to run the laptop.

Question: How Do We Recharge a Laptop Battery

Answer: a)You do plug it into a wall socket but please be sure to use a surge protector between the wall outlet and your power adapter. Recharging a laptop battery without a surge protector is a quick and easy way to damage the laptop.
b)You can use the laptop while it is charging, there is no problem working that way.
c)If you aren't going to be using the laptop when you want to recharge the battery, then turn it off. There's no need to leave it running if it isn't being used.
