Needlessly cycling the battery by unplugging the external power supply once the battery is fully charged will wear the battery much faster than leaving the laptop plugged in whenever possible. When the external supply is plugged in, the battery is not involved in powering the laptop as the two sources are diode OR-ed and the external supply's slightly higher voltage wins.

Modern laptops are not like the old ones, they have fail-safe mechanisms and better electronic charging cicuit so that when the battery is full it cuts the power to it and it only powers the laptop leaving the bettery in stand-by just like physically unpluging it. No need to worry about this on any modern notebook.
Yes on old notebooks it would keep pushing power into the battery until you unpluged it, this is not the case anymore.

Lithium batteries tend to explode or catch on fire when over-charged. If devices with lithium batteries didn't have over-charge protection, they would be far too dangerous for use by regular people.
