I'm Using Asus X42DE Notebook and the battery was replaced a week ago. OS is win 7 home premium. I usually keep it plugged when I work so it will decrease reducing charging circles. But when it drops with time to 99% then to 98% and shows 98% available, plugged in charging. And when it goes below 98% while plugged in, it shows like 97% available, plugged in charging.but actually does not. it just maintain in the level. It only charges for real only when battery level is below 95%. is it normal? Thank you!
