How can I add Bluetooth to an Acer Aspire 1680?

[FatRakoon]

I got an Acer Aspire 1680 LapTop.
Its got all the junk for Bluetooth, but no actual hardware?

So...

I have gone out and bought a Bluetooth module.
But, I really cannot find anywhere that it can go?
I have tried looking around the web for any helpful info but I have failed.
I just dont know what to do next?, and Im completely lost.

Anything?

Erm, its
Aspire 1682WLMi
Model ZL1
