Upgrading Memory

I am trying to upgrade my laptop memory from 256 to 1gb.

The current memory is a 256 MB PC2100 DDR SDRAM card.
I bought Kingston 512MB 200-Pin DDR SO-DIMM DDR 333 (PC 2700) to upgrade it.

I was just wondering my laptop would support it. I have seen two different things. One site says it does support the PC 2700 and one site says it does not.

Can anyone help tell me if it would work with my laptop?

If the computer does support it, can I put in both cards at the same time?
the 256 MB PC2100 DDR SDRAM card AND Kingston 512MB 200-Pin DDR SO-DIMM DDR 333 (PC 2700), since I already bought it?
 
It should be fine, both are DDR, the faster stick will be clocked down to the speed of the slower one though.
 
Yeah you can, but you have to be careful. I don't know if its the same with laptops, but for desktops you must put the slower ram in Slot 1, that is the slot closest to the CPU so it gets recognised first. Otherwise if its the other way around, the motherboard will try to run the ram at the fast RAM stick's speed and you will get crashes and errors because the other stick can't keep up. I'm not sure about laptops, just test it out. It wouldn't permanently damage your system either way.
