If 2gb is the max, what do I have to replace to get more ram capability?
Unfortunately there is nothing you can replace to increase your RAM if you already have 2GB. The limiting factor is the motherboard and BIOS for that model of notebook.
Most notebooks have custom made motherboards with a custom made BIOS file. The company will only release one BIOS file because there really is not a reason for another.
My recommendation is to NOT buy the 4GB of RAM right now for a couple reasons:
1. 2GB of RAM is just fine and will complete 99% of all tasks that you could possibly do with that notebook anyway. I have 2GB in my notebook and I edit photos and game with it...smooth as silk
2. If you really want to upgrade...find a friend who has 4GB in their notebook. Slap that RAM in your notebook and fire it up. If it starts, do some stuff with it (open a few word documents, look at some pictures, ect...) If it runs fine, then buy the upgrade
I found out the memory type is- PC2-5300 DDR2 SDRAM SODIMMs and they make 4gig sets for that type of memory
Other notebook manufacturers may be able to run 4GB of that RAM in their notebooks.
Your notebook takes PC2 4200 or PC2 5300 according to the spec sheet StrangleHold found.
