1. To replace your internal hard disk, you can buy a 2.5" SATA Internal HDD at your local computer hardware store. I personally replaced my 250GB one with a 500GB one. It cost about $100.
2. To replace the RAM, simply follow the instructions at ifixit.com. Depending on your usage pattern, 2GB may or may not be enough for you. If you:
a) Simply browse the web, read email and edit documents, 2GB is enough.
b) Play some games, do graphics designing with Adobe Suites or other software, you may consider the upgrade to 4GB.
Depending on your macbook model, the computer may or may not support 8GB of ram, but most people don't need that much.
IInterestingly, Apple says no Macbook will support more than 4GB Ram but the youtube video has the dude installing 8GB.
Ram is so cheap at Crucial and OWC, and so easy to install, do it yourself. If you have last Macbook made, be sure to keep tract of the 8 screws as they are of different lengths and will drive you crazy putting it back together
Go to "Apple Menu > About this Mac > More Info" ... mine is "MacBookPro8,2" below ...
Then you can use "everymac.com" and enter the "model identifier" to see more information about the full extendability of your Mac, Apple's original specifications are based on available RAM at the time of original sale or availability of "reasonably priced" RAM at time of original sale. "everymac" lists currently-tested capabilities af your mac.
Thank you for your reply.
I have a:
Model Name: MacBook
Model Identifier: MacBook5,1
Processor Name: Intel Core 2 Duo
Processor Speed: 2 GHz
It seems looking at everymac.com that 160gb is the recommended size (although mine says capacity 150gb).
So would it be ok to uncrease to 250gb?
Another post to my questions it states that 2gb Memory is fine for what i do ie email, surfing etc. Would you recommend keeping at this?
Thanks for your help.
