I am wondering if it's hard on the laptop battery to leave the laptop on all the time?

Here's what I know and this information came from a good friend of mine who's pretty good with computers and gadgets. It is best to unplug the charger when the battery is full 'cause it might shorten the life of the battery. Although some laptops indicate that it is not charging, a little bit of current still flows through the battery. Personally, I have my laptop batter charged only if I know that I would have to go somewhere else and need to bring my laptop. But, if I'm just at home, I actually remove the battery and have my laptop plugged in directly to the power source. Still, I make sure that I have my battery charged at least once a week to keep it functioning.

That sounds like good information and not a bad idea about taking the battery out. I have heard of them exploding and so forth. I just unplug mine and run the battery for a while. I have no idea what the life of the battery is or how much they cost. Guess I will find out one day.

Well in theory if your laptop is plugged in all the time the battery will recharge if required and then the charge controller should disconnect the battery, or switch to trickle charge just to keepit in tip top condition, that's the theory. In my experience, I've seen around 7 laptops kill there batteries after about2 years in our office, where they are coinstantly in docking stations, seems a lottle odd to me, but doesn;t prove anything, it may just be a fault with that model.

From what Ive heard its much better for the battery if its first recharged full, then unplugged and ran untill the battery runs out and the laptop shuts down and then recharged again. It keeps the batter better.

Hmm, I've never heard of that before and I've actually heard that it can be good for desktops to be left on so it could update software and stuff. I know that always leaving your laptop plugged in will kill the battery for sure. When I first got my current laptop, I used up all the battery before plugging it in to charge. But, I've been bad since then and I've left it plugged in way after it's finished charging and now my battery life isn't so good anymore. It also depends on the size of your laptop. My screen is 15 inches but my friend has the same exact laptop only with a 13 inch screen and her battery life is a lot longer than mine.
