Replaced 2 512 mb with 2 1 gb's.
Called Dell 10 days ago; got great live service; she walked me through what my two computers now had; what was needed; shipped the parts UPS.
Then http://www.dellsupport.com/ provided me with the manual for my laptop and http://accessories.us.dell.com/sna/Dell PartsFamily.aspx?c=us&cs= and some more which has an ambiguous letter, but you can find it...has a movie which just shows how to ground yourself before handling the parts, but shows exactly how the new modules click in with a firm click so you know you've done it right.
Now, after powering up, everything is quick, quick.
It's like gaining ten years of life. And I had a good laptop before this!
I feel like I've just climbed Mt. Everest!
