I have a Toshiba Satellite A10 and had a look last night. I thought it would be in the instruction manual, but it only tells you how to unscrew the memory bay on that. I'd be careful though; it appears that some of the screws that need to be released are marked up F5, and some are marked up F16, and i think others might be underneath the model number label and some under the Windows XP certificate of authenticity, on mine at least.
