I called HP support the other night after I found a deal on memory for my laptop. I was wondoring if it will fit. The guy said that PC2700 SODIMM memory is the same as PC2700 SDRAM for my notebook. Is this guy wrong?

Basiclly he is right:
SDRAM = Synchronous DRAM
DRAM = dynamic random access memory

SODIMM = Small Outline DIMM (commonly in notebook computers)
DIMM = dual in-line memory module
SIMM = Single in-line memory module

You also want to make sure to get the correct Pin & Speed.
