Okay, I'm helping out someone, and they have a Dell Inspiron 1525 laptop that's running Vista Home Basic on 1GB of RAM, They say their computer is slow. I'm thinking that they could use more RAM on their system, and it might fix their speed problem.

Now, I pulled up the system configuration info, and discovered they are running off of 2 sticks of DDR2 PC2-5300 512MB. My questions are these:
1. Is the RAM on an Inspiron 1525 replaceable without having to pay Dell to replace it?
2. If they were willing to upgrade their RAM, what speeds of RAM can their computer handle?
3. If the RAM is replaceable, how do I gain access to it?

And assuming that the RAM is replaceable and that I can access it...

4. Got any recommendations as to what brands of RAM to get?
