That is my understanding. The 600
E systems have 32MB onboard. SDRAM=Synchronous Dynamic RAM. SODIMM=Small Outline Dual In-line Memory Module. They really don't mean the same thing. SDRAM is the type of memory architecture used, whereas SODIMM is what they call the form-factor of the memory module.

Yes, for 600X systems (64MB onboard, plus two 256MB modules).

Keyboard and screen will work, motherboard will not.

Each system from the factory could come with different options: processor, memory, operating system, CDROM vs. DVD, etc. etc. etc... That's mainly the reason why there's so many different type designations. If you have the type number, just plug it into the Lenovo link I provided earlier and you should see the important system specs.

See my .sig below. I like them. Sturdy, almost bulletproof machines, great for general use (web surfing, word processing, etc.). Only "downside" I find with mine is the single USB 1.1 port. Actually, it's the same beef I have with the T23's as well, except twice as much
