This is what happens to your battery when you don’t read the signs. If it’s not charging or telling you to replace the battery. Maybe it’s time? Before it explodes or expands you note book destroying to casing. Believe it or not I have seen it bend metal. If it’s not holding charge its technically becoming an element (best known for heating your house or a stove) and overcharge can cause an explosion. The Average battery replacement for a PC is $95 and $149 for a Mac. Get working away from the power point again and update your Battery.
