Why does failing to fully drain a laptop battery "condition" it to having a smaller lifespan?

Are you sure you're not confusing lithium ion (laptop) batteries with nickel metal hydride or nickel-cadmium batteries? Voltage depression (sometimes erroneously called a memory effect) from partial depletion is not really a concern with lithium ion batteries, though it was with NiMH and *especially* NiCd batteries. Draining a lithium ion battery entirely will help calibrate the battery sensor, but won't help the longevity of the battery itself (in fact quite the opposite).
