Hello, Need to check about macbook battery. I had charged my macbook battery 100% on the first day when i bought. After that i just use the AC power supply whenever i am using the macbook as i never bring out of my room. Now the question is when i fully charged it was 100% then the following day it dropped to 98% and today it was at 97% even though the status show as "Battery is charged" and the indicator light at the magsafe connector always show green despite the drop in the battery level. What i understand is that the indicator light will turn amber when it is charging but how come when battery level drops to 97% and it is not charging and always remains green? Any help here is greatly appreciated. Thank you.
