How old is that MacBook and what colour has it? Can it display something on an external display?

A more descriptive and precise thread title will help cater to the right audience and get you more adequate responses. (see rule #3 under How do I get help with a hardware or software problem)
To edit your thread title, just click on the

button on the bottom right of your original post and then click the "Go Advanced" button below your message.
Have you also taken a look at MRoogle, since that question may have been asked several times?
