I'm using Fujitsu S2020. It support DDR PC2100 SDRam... I bought a Kingston DDR PC2700 SDRam and slotted it in but it just doesn't work no matter how I try... I tried to put the Ram in another computer but it works... Help!!! Anyone?

I thought Ram suppose to be backward-compatible?

I bought Kingston.... So sad... Luckily the other notebook can detect... If not... $$$ down to drain...
