I doubt it, as I n++ your n=1 by experience, but also since I think it shouldn't be hard, electronics wise, to stop charging once full (or even, optionally, 80% / 90%) and fully run on AC as long as it's available. Also I'd say this is an apparent user requirement for laptops.

Battery vendors generally recommend you do not keep them on a charger all the time since the charger will keep it at 100% charge, and the longer a battery is at 100% charge, the more degradation it will experience for electro-chemical reasons. Sooner or later, that can lead to battery swelling and eventually a catastrophic thermal runoff.

Additionally, keeping a laptop shut and running usually messes with its thermal design as the heat can't escape to the top via the keyboard, further heating up the battery.
