If the BIOS still sees the drive, maybe.  If not, you'll need a data recovery service and a couple of thousand dollars.

 

If the BIOS does see a drive, remove the drive, mount it into a 2.5" USB 2.0 case and attach it to a working system to see what you can read.

I wonder.

If you can purchase a working hard drive of the same size, can swap the platters yourself if your tech savvy.

Might not have a clean room, may destroy a drive/kill it life, but a lot cheaper than a few thousand $$$ to try and get the info...

I forget, doesn't Dell want the old drive back?

Just a question if possible. Were there any signs of hdd failure before it "died"? I am asking this because i hear some "clicking" sounds from hdd area :D.

No, no signs at all, I just tried to boot up, and it just wouldn't, no noise, nothing.

Thanks for your suggestion, but I am not that savvy. To put the new hd in is no more difficult than changing batteries in most electronic gadgets, but I don't want to go any further. And Dell does want the old one back.
