The keyboard does not work properly.
He seems to be slow sometimes, for example when I type, some letters do not appear.
This problem does not occur all the time but frequently.

The trackpad works just fine.
This makes it difficult for me to write a report.
What can I do?

MacBook Pro, Mac OS X (10.7.3), bought in (Sep) 2011
