I have Lenovo G570 laptop. It has started showing some problems with charging. First, I assumed it was hardware problem but now after some observerations I realize it's something else.
Once charged fully it works till entire battery is exhausted and then after almost 50 hours it starts charging again. It's strange for me because since almost 2 months it's same schedule. Also, after fully charged, when battery is in use, if I try to charge in between it doesn't accept charging. All the time I have to keep it plugged in.
I tried to uninstall "microsoft acpi controlled method battery driver" but no help. Please let me know.
