One cell of the battery apparently was never glued in and is rattling around inside the laptop. Is there any harm in crazy-gluing it in place?
Maurice Volaski Don’t use “crazy glue” because it will be a PITA if you ever have to remove it. It will predispose you to doing a whole lot of damage. If you got to glue it use some glue you can easily remove. Take a look at some 3M or Tesa glue strips as well.
