Bios Reset Dell Notebook

[S8n]

Does anyone know how to reset the bios to default values on a Dell XPS L501 Notebook?
My machine currently wont get past the startup splash screen, wont go into bios at all.

PS: Already tried removing the battery and holding power button to discharge.

Thanks

Thanks Howard, I did try that one. Didnt reset anything.
After spending 2.5 hours on the phone with Dell's Tech support, they're sending out a technician tomorrow, with a replacement HDD, Mobo and CPU. So I'm holding thumbs its one of those.. I'm leaning more towards HDD thats fried, as the part where the system hangs is when it starts to detect drives, and if I pull the ram out, the mobo moans at me, which is a good sign.
