Can i connect a Notebook via S/PDIF?

hi buddies....

so i had finally purchased Philips home theatre HTS3565/98.
I had also auditioned yamaha YHT-185

i found both at par so i went with philips.
anyways thats not the point....

I have a DELL notebook inspiron 1520.
It has S/PDIF out.

now i was wondering can i connect my notebook to my philips HTIB via digital coaxial cable since the HTIB has Digital coaxial in?
will S/PDIF on laptop support this digital coaxial cable?

if yes will i be able to achieve 5.1 surround sound on my HTIB?
what are the other accessories i need to buy???

thanks a lot for ur support.

Regards
