Laptop has no power ----HELP!

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.

 

Hi and welcome. Since you were playing around inside, my suggestion would be to check connections and the ram to be sure you didn't bump something loose.

Along the lines of the cpu fan, if you fried the cpu..........
