Wait, what? Leaving the laptop will harm your battery life? Just who told you *that* little gem?

Also, you might look into the fact that your computer is probably throttling back the CPU and / or GPU when running on battery power to help conserve the battery.

Even a new lithium ion battery will wear out prematurely because of excessive heat if it's always plugged in and fully charged. You can remove the battery if you plan to leave it plugged in for an extended time, but drain it to about 40% first. Another option is to change to the high performance setting in power management, then go into advanced power settings and set it up as shown below:

Setting it up that way will probably only give you about an hour of game playing time on a fully charged battery, a little more or less depending on your hardware.

madtown,

Your answer makes a lot of sense and I agree for the most part, but I'm not exactly sure about this part....

This sounds more precautionary than anything else. Wouldn't insuring adequate ventilation be the better option?

Anyways good answer +1

Last I checked, laptop transformers don't supply charging voltage (only trickle voltage) to the battery when it is fully charged. I am not sure how this could cause any sort of over heating....

If the laptop itself overheats, then you have a much larger problem to begin with - adequate ventilation, and mentioned by sygnus, would be the solution there, but that is always dependent upon the user - if you choose to use the laptop in a manner that restricts ventilation, then you're not only harming the battery, but shortening the life of all heat-dissipating units in the laptop (CPU, GPU(S), etc.)
