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!

Update

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!

Update

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

Did you turn to the right or left on the jump?

a joke, a reference to your jumping 3 times

Double check if all the screws were installed at the right locations when assembling the MBP after the HD swap.

This could be a lot of things, thus we may need to try a lot of things. Be patient. First make sure the battery is charged up by charging for at least an hour. We have to be able to boot to fix anything. Try this:

1) Shut down MacBook and remove the battery;

2) Hold down the Start button for ten seconds and then release it;

3) Reinstall the battery

4) Restart the computer

This procedure resets the MacBook's PRAM settings which contain many of the computer's basic settings, including the RAM disc which needs to be accessed for the computer to awaken.

Try starting up with a system installation disk with the disk inserted and holding down the "C" key. Try with the disk and holding the "D" key. Try starting holding down the "shift key" and starting. Try starting holding down the Option, command , P & R key and hold for 3 tones then release. Did you get any results?

Battery was at 3 dots and I reset the PRAM, but no dice. What's next on the list?

(BTW - Thanks a ton for the help! I'm happy to work through it slowly and methodically.)

mayer:

The power won't turn on at all at this point, so I can't insert the disk. I tried the key combos anyway, but didn't get anything.

lemerise:

Double checked, but all the screws are in properly.

Do you get a light on the power plug (magsafe)?

When you turn your computer on, does the screen turn white / light grey? If so is there a logo in the middle and what kind? Does it make the "dong" sound at any point or does it make any other sound? If you turn it on while holding down the "T" key will the computer go into target mode (firewire symbol bouncing on the screen)?

dealing with a similar problem today. In another forum (apple) I found others. I then tried as advised and started in firewire-target-mode and there I hat the HD on my desktop. That means logic board must be ok - but NVIDIA-card seems the one to blame.

A happy start to the new year since I got the (mid 2007) MacBook Pro only today - at first it had worked, then I started to upgrade to 10.6. never touch a running ... hr
