Hey I am new user of a mac. my macbook pro is excellent. all i want to know is when my laptop is charged to 100% it says 2:30 remaining. then after 5 mins it says 2.05 remaining. i am using the high performance setting (NVIDIA GeForce 9600m GT) and even in that mode it should give me upto 4 hours right as mentioned on the apple website. i have only had this macbook pro for 3 days now and charged it fully the first time and have been working on it with the charger plugged in. another question although the batter is 100% charged do it damage the battery if i continue to use the macbook with the charger plugged in?
