That's your problem. You're destroying your battery on your own. Laptops aren't designed to stay pugged in at all times. You crystallize the battery since you're not using it's full capacity. By leaving it plugged in, the battery will repeatedly die 5% and then recharge while never using the other 95% of the battery. Over time that 95% crystallizes and becomes worthless. You MUST allow the battery to die at the very least 1-2 times a month to keep the battery in a healthy working state.
This goes for cell phone batteries as well, or any li-on battery.
