You need to go to the system manufacturer's website on a manufactured system and the motherboard manufacturer's site on custom systems and look up the CPU Support List. If it is on the list and the BIOS version you have supports the CPU, you are fine. If the board supports it but your BIOS version does not, then you will need to update your BIOS. If it is not on the list, it will not work (or at least not work properly). Since you have not supplied this information, we cannot help you further. Either supply all of the information or look it up on your own. There is no other way of telling, guessing is not the right way.
You have to be a little bit crazy to keep you from going insane.
What are your plans for this old laptop? It's not a good candidate for Win7. You can max out the RAM at 2GB & upgrade the CPU, but it still only runs at 400MHz FSB plus the Intel Extreme Graphics 2 suck. Are you still running the 30GB HDD? I suggest you stick with XP or try Linux.
