I am encountering this problem as well now on my 2009 17 inch Macbook Pro.
First day it was sufficient to hit it a few times till it went away, but it got more persistent and persistent during the weekend.
Now it seems 'fixed' by making a custom laptop stand which applies pressure to the bottom right under the eject-button and at the battery indicator lights. Tomorrow I will let a few geeks at my faculty look at it and hopefully solve it.
Gary, Nick and Mark, can you give me (or the geeks) tips? What worked?
PS: the screw in the bottom plate nearest to the power-inlet has been gone for a year or so, but it seems unrelated.

I took a look at the connector of the dipslay data cable to the logic board, which looked perfect, reattached it and screwed it back together, no result. It's still the same. Any ideas anybody? I can't really cough up the dough to replace this laptop and it feels like it is really easy to fix if you know how to do it.
