Should laptops remain plugged in when their battery is 100% charged?

I have an HPcompaq nc6400 but I don't have much information about batteries.when I'm home I run it on electricity so at this time should I take the battery out or it's OK if I run it on electricity with battery on?

Well, it's okay for short periods of time. (e.g charging it back up while running.) However, the heat a laptop generates adversely affects lithium ion battery chemistry and causes it to lose capacity (as it does naturally) at a significantly quicker rate.

So, for the longest possible battery life, you will want to remove your laptop battery when working on AC for long periods of time.

Leave the battery in. It'll recharge while plugged in bypass the battery once fully charged.

The battery will charge as needed and the system will not draw off of it when it is plugged in, appreciably.

Leave the battery plugged in., it won't hurt anything.
