e-system memory upgrade (revisited)

I bought one of these a few years back, in the full knowledge that it was supposed to be possible to upgrade the memory to 2Gb. Initially, I replaced the installed memory (512M) with a 1G module, and would have installed the full complement if I had been able to do so. Sadly, it would appear that the second module has to be fitted to a socket under the keyboard, and I would desperately lik to find out how to do that. I note from previous messages on here about this type of system, that this is not at all straightforward; so I am am now looking for any useful information to assist me in completing this task.

Any suggestions would be most welcome.


Thanks
