Stop using your laptop immediately. Bring the battery to Best Buy or another electronics recycler. These can explode and spray caustic materials. The "puffing" is a safety measure to contain the bad chemical reaction that has already happened and killed the battery. You have been warned!

Laptops usually work even without battery (only when pugged in ofc). Since the cover is off already, just remove it and go on with your day till you have time to find replacement.
