Laptop Memory Upgrade - Swapping memory?

[pastorbillcochran]

I'm looking to upgrade my laptop memory from 3GB to 4GB. I have extra cards from another laptop and wondered if they are compatible.
Extra memory is: 2GB 2Rx8 PC2-5300s-555-12-E3
Can this replace:
2GB 2048MB-667MHz DDR2-667 PC2-5300, 200p SODIMM, 1.8

It should work. Both are;

200-Pin DDR2 SODIMM
PC2-5300 - 667Mhz
Non-ECC Unbuffered - 1.8V
