When I bought Lenovo Y480 recently, it came with Windows 8 pre-installed. I have been using Windows 8 in the Battery Optimization Mode (where battery only charges until 59% for longer life). Now, something has some gone wrong with Windows 8 and had to install Windows 7. Now I have two problems -
1) The battery only charges until 59%. What/Where do I change to get the battery charged until 100% ?
2) While discharging from 59%, the charge goes to 58%, 57% and then suddenly drops to 6%. Overall I get a battery life of 5 minutes, at maximum. So, is the battery damaged? Or is it due to the change from Windows 8 to Windows 7?
