This page has a good answer: "it depends" The answer is: YES and NO, it depends on the situation. Having a battery fully charged and the laptop plugged in is not harmful, because as soon as the charge level reaches 100% the battery stops receiving charging energy and this energy is bypassed directly to the power supply system of the laptop.
If you want to minimize the full-charge duration, consider putting your laptop to sleep (rather than hibernating or powering down completely) so that the battery discharges a little overnight. ALL laptops, and everything else that uses Li-ion batteries for that matter, stop charging the battery when it's fully charged.
More of a topping-off when the voltage drops again. Some laptops permit operation with the battery removed from the battery bay. In addition to stopping charging, it prevents exposure to potentially damaging heat—heat is the main contributing factor to premature failure of laptop batteries.
High voltage levels while charging can shorten a battery’s life, and temperatures over 30° Celsius can also severely damage it. According to a study by Battery University, you can prolong your battery’s discharge cycle by not charging it to 100% (4.2v charge/cell).
Modern devices stop charging once the battery reaches its maximum capacity. If the battery loses some charge, trickle charging supplies a small amount of power to top it up.
The laptop uses ac adaptor when plugged in. Not battery. If you take a look at the battery icon when plugged in, you would see it goes to 100, then gets discharged to some level and charging back again. So the simple answer is that laptop does not use power from battery when plugged in. Battery gets charged and discharged. Does this kill battery?
