Something got underneath my trackpad button

[Ravich]

This is an early 2008 MBP, so I have a button separate from the track pad. For the last several days it has been most of the time clicking twice when I press it. The first one doesnt do anything, the second one actually clicks (that is, if I dont push it all the way down it clicks the first time and doesnt do anything, if i push it harder, it clicks the second time).


What can I do about this?

This may sound strange, but check to see if your battery is swelling
