This is kind of a noob question, but hey this is my first laptop.

So I have a G46VW and it has a non removable battery and since right now I'm not in the US replacing it can be a pain. So I want to be keep it safe and working for a long time. Well, we all know gaming without plugging it in is impossible, so consider the fact that the laptop to be plugged in most of the time, before answering the question.

The question is what is good for the battery? Do I keep it plugged in all the time? Do I charge it fully then run it on battery till its battery runs low and keep doing this cycle?

I've googled the topic and so far hasn't got anything solid. I have found that discharge cycles are not recommended for Li-ion batteries, and that plugging it in all the time is infact good. Is this true?

Also a more technical question, when a laptop is fully charged and plugged in, does it directly run from the supply while keeping the battery on the background or does the battery still remain invovled in the circuit?

It's true that the old fashion discharge cycles are not good for today's laptop batteries. The new Li-ion has the longest shelf life half charged. Shortest shelf life discharged. And decent shelf life fully charged.

So if you are not going to use the laptop for a while, it's better to leave it half charged. If you use the battery, try not to drain it all the way down too often. And if you use AC all the time, well, not much you can do other than enjoy it.
