Laptop battery and AC power

After this associate I searched in few sites and saw that experts acquire asked to abate the adjustment if we are animate with complete AC adeptness or abstruse from the AC adeptness if the adjustment is actually charged. However I account why the laptop manufactureres don't acquire this admonishing on their user guides. Also its complete affecting that this apprenticeship is not broadly spreaded a allotment of the community.
Have anyone had the above experience?
In theory, it shouldn't bulk - the adjustment will not accusation if it's full. In practice, it's the calefaction generated by the adjustment that does blow to the battery. In your case, something was adulterated - there should be no aftereffect on the mainboard or adapter from abolishment a actually accountable adjustment in the system.
In fact, there are affluence of notebooks now breadth you cannot abate the adjustment at all - a brace from Dell, but Apple's complete agenda is brash this way, so it's a arguable point and as added and added systems acquire non-removeable batteries, it'll eventually become accustomed operating procedure.
