I have a new battery pack for my acer aspire 4750 laptop, it hust a 2 weeks old, actually it is working pretty good.
I use batterycare to check charge level, so while i am charging and it reached 80% I remove the AC, then recharge it again at 40%.(the batterycare will show a pop-up if I reached 80% or 40% of the battery charged level)
But since yesterday i got these problem, the batterycare and the windows battery indicator notifying me that the battery is already full charged, but when I unplug the AC adapter, i can see the batterycare report and windows battery monitor that the charged level my battery is just 78%.
It doesn't even reached the battery care notification for 80% charged level.
Any idea about this?
I will appreciate for any help will come.
