laptop won't power on..

Hey all,
I have an HP Pavilion n5415, which does not power on, at all.
no lights, noises, nothing. I have tried with the plug, without the battery, etc..
It powered on until yesterday, I removed the hard drive (which was dead), to extract some important info, put it back in, and now nothing.
Just a note, it was making some crazy sounds prior to this whole thing, it sounded like the cpu fan was hurting, but still, shouldn't there be some sign of power now?
Thanks for nay help.

Can you try with the HD removed. Any difference?

One trick is said to work on some laptops:
Remove mains power and main battery. Press and hold power button for 1 minute. Release, reattach power and try.
If the cpu fan died, that might be the reason it doesn't power up anymore, because almost all AMD motherboards care about that and won't start without a working fan.  Replace the fan - if you are handy, you might be able to do this yourself, or get a shop to do it.

Hey Rid, thanks it worked!
It's now making the dying cow noises just like before!
Thanks again, oh and Callandor, I'll put that in the notebook in my head.
"... dying cow noises..."  Hehehe, right. Fan bearings worn out or dried up. New fan indicated.
