That big thing on the underside...
I am getting two old RAM sticks from a friend who bought his MPB two months ago.
-His is a Santa Rosa MPB
-mine is a first gen Core Duo Macbook
-he's giving me 2x 1GB sticks (that I want, I have 2x 512, he now has 2x 2GB to give himself 4GB)
-It's the same pc2-5300 at 667 MHz, so I know it's compatible.
What I want to know is besides turning off the laptop, replacing the RAM and turning it back on, is there anything else I do (since it's used I don't know if I have to do something extra, I know with new RAM, you just replace and go).
Also, (if I ever need to go to it) does the Apple Genius bar frown upon replacing your own RAM, because I heard they do, even though they post the instructions on how to replace it on their website.
