MacBook won't come out of sleep (or turn on)

I replaced my hard drive with no problem, but I think I may have done some damage in there while doing it.

When the Jupiter is in the proper alignment with Mars and I jump 3 times and spit, my laptop may start up. I close the lid and the front LED does it's proper glowing thing, telling me that it's properly asleep. When I open up the lid again, nothing happens. The intriguing thing is that if I hold down the power button, it will shut down, so clearly the keyboard is functioning (or at least the power button). However, once I do that, I can't get it to start back up again.

My assumption is that the laptop still thinks the lid is closed. Anyone have any other guesses? And if I am right, any ideas on how to fix that?

Thanks all!

Just to clarify:

The laptop worked just fine for a while, but then ran into the trouble I mentioned in the original post.

At his point, the laptop won't turn on at all...no glowing light, no whirring of the hard drive, no fan, nothing. One in a blue moon it happens to turn on, at which point it works fine until I close the lid and then it stays a glowing light with no ability to get it started back up (regardless of if I lift the lid or hit the power butt).

Mayer: I'm not sure what you mean by jump. Could you clarify?

Thanks everyone for the help so far!

magsafe light turns on just fine as do lights on the battery.
