Upgrade memory – Notebook

Hi,

I have a Sony VOIO PCG-C1MT notebook. Current memory is 128MB and I would like to upgrade to 256MB. I just bought a 128MB memory card for this notebook and I would like to install myself. Can somebody guide me how to do it? I’ve seek advice from Sony but none of them are willing to help me because I bought the memory from third party. I’m quite familiar with PC hardware but not notebook. Appreciate you can advise.

Thanks
