I have a lenovo ideapad (Y450) that I had not been using for some time. I started using it yesterday and formatted the OS from Windows 8 to Windows 7. It was working fine till night when I noticed it showing 'battery not charging' when being plugged in. I didn't pay much attention and went to sleep after shutting it off but kept it on charging.
Today , I tried turning it on but it didn't. I observed that the light in the charger is blinking when plugged into laptop but otherwise is a solid green. I took out the battery and then plugged in the charger and found that it is still flashing green and the laptop is not starting.
So, the light is solid green on charger when not plugged into laptop.
It is blinking green when plugged into laptop with and without the battery in.
Any insights on what the problem can be and how I can fix it would be greatly appreciated.
