I have a Fujitsu LifeBook T4210 Tablet PC that I bought new and has about 1GB of RAM in it when I bought it. My computer is about two years old and does not run as fast as I would want it to run so I wanted to buy at least 1GB of RAM to speed up my computer. I went to BestBuy and bought a Kingston 2GB DDR2 (667MHz, PC2-5300) notebook RAM for about $57. I took it home, followed the instructions (which is about 3 steps long and very simple) and it worked. The guy I talked to at BestBuy said that some laptops may not be able to use more than 2GB of RAM. However, the LifeBook did accept the 2GB of RAM plus the 1GB of RAM I already have making a total of 3GB of RAM for my laptop. I highly recommend buying extra RAM for your computer if you have the LifeBook T4210 because it has made my laptop significantly faster.
