That is an old laptop, even if possible to upgrade it, it would cost as much to repalace it with a faster one than find parts to upgrade it.
You are probably asking the wrong question anyway. What are you trying to upgrade it for and what is your budget? A lot of people tend to ask the wrong questions like "where can I find a bucket so this blood does not get on the floor" instead of "where can I find a bandage and a doctor".
To give you an idea of what I've got planned, here's a list of current hardware along with upgrades I'm looking at:
Current:
-AMD Turion X2 Dual-Core Mobile RM-72, 2.1 GHz
-4 GB (2x 2GB) DDR2-800, SDRAM
-320 GB HDD
-ATI Raedon HD 3200 Graphics
Planned upgrades:
-AMD Phenom II N660, 3.0GHz
-Komputerbay 8 GB, (2x 4GB) PC2 DDR2-800
-Seagate 1 TB SSHD
-graphics card is not upgradeable
From what I've researched these upgrades are compatible with my system. I figured the graphics card is the last thing, but if it's non-upgradeable then that's the way it is. Thoughts?
