Toshiba satellite a65-s126 memory

[fulladv]

I am the proud owner of a Toshiba a65-s126 laptop. The specs say the maximum memory is 1.5GB but I would like to go beyond that if possible.
The "fixed" memory slot has a 256kb module installed and once again the
specs say it is not replaceable. Has anyone out there changed out the 256kb for example a 1GB and then tried a 1GB in the one available memory expansion slot? I did something similar to this on an IBM laptop I used previously with no problems. Thanks for any and all ideas.

Did you have any luck with your ram problem? I have the same laptop and i was wondering if yours has 2.8 ghz celeron northwood. Also do you know what is the best processor for our laptops? I would really appreciate a response mine is running really slow. Thanks
