OK well heres the deal. Currently my macbook is charging and it's at 33% and it says it has 7 hours remaining until it's complete. iStat tells me that my battery is still 100% with 70 cycles. My macbook is only 6 months old, and this battery issue started happening just a few days ago. Could it be the charger? sometimes i plug in the charger and the light doesn't come on sometimes. Also something odd that i noticed, when my charger isn't plugged in it still says its power source is from the power adapter. Could it be from using my parents macbook pro charger on my macbook?
