Laptop batteries generally provide a fixed number of charging cycles and are constantly losing a part of their charge. As a lithium-ion battery placed unused within a PC, running off the AC adapter, the PC heats up. The hotter it gets the quickly the battery discharges. If the battery remains within the laptop while running off AC power continuously, it is in a continuous position of charging and discharging, unwontedly consuming power. It might be possible to service the battery and get extra charging power.
