I have read in a website that the proper use of a battery is to drain it before you charge or plug the ac adapter to the laptop. Or if you prefer to use the charger, take off the battery. That's how I usually do with my laptop and it's almost a year now and so far, I don't have any issues with my battery. You can also try to flash the bios, sometimes it does work but try using the battery the way i do. When you're at home, use your laptop by just connecting it to the charger without the battery.
Hope this works for you.
