Well, there are two schools of thought in my book.
Each manufacturer will have different ways of monitoring battery level.
In the olden days, the machine might take 10 mins pumping an unnecessary charge before it calculated a 'full' reading. This took a strain on the cells and reduced the life of the battery.
I used to take battery out when using long periods on mains.
Modern battery (li-Ion) and charging methods (superior sensing) have changed and I now just leave the battery in when on mains.
It shows as complete charge and relies on mains only. This protects the battery from little trickle charges.
I still often run the battery down completely before a full charge only situation. On the last 3 laptops I have had over the last 2 years this seemed to work well and the batteries were 'fresh'.
