Apple: solution for MacBooks with battery problems

Some weeks ago I had a problem with my battery (MacBook). It was just unable to charge and the computer could not detect a battery on the system. It was just displaying an "x" where normally was the battery icon.
At that moment the solution was to replace the battery. I went to my local Apple store and after some days I received my new battery.
But now Apple released an update that can solve that problem: click here.
