Something strange with my swap partition

[Isidoro Reyes de Zuloaga <isidoror@salleurl.edu>]

Hi again.
Now i'm trying to fix a problem with my swap partion. First when i installed 
my debian (sid) i made a swap partition, but i think it's not working because 
if i run free it says:

yoda:/home/isidoro# free
             total       used       free     shared    buffers     cached
Mem:       1034240     392544     641696          0      31676     240140
-/+ buffers/cache:     120728     913512
Swap:      1535992          0    1535992

I think it's not using the swap partition. Can somebody help me?
I don't know how to find it at google..
thanks in advance.
