I would highly highly NOT recommend trying to take apart the S-series - it's just not worth the headache, and the chances of breaking something are very high.
Not worth it, in my opinion. (And I've had three S-Series and been through this.
There are better, easier to modify/upgrade, and cheaper laptops out there. (ex. HP L2000 / Compaq V2000z)
(That said, your guide is welll done and I commend you on it).
