Ask Max: Adding RAM to a 12" PowerBook

Asked on 05/26/2006:

Hello Jacob! Well my question might be a stupid one, but I have been trying to figure it out for a while now. I know that PowerBooks are able to have up to 2 Gigabytes of RAM, but when you buy it the max you can get on a 12" PowerBooks is about 1.25 Gigabytes. How do you change the internal memory? I know how to change the removable memory but not the internal. I figure that the only way to get 2 GB of memory is to change the internal as well. I bought a 1 GB stick of memory but my PowerBooks only has 1.25 GB's of ram. How do I get 2 GB?


The 12" PowerBook is not like the other, larger screened, PowerBooks. It has more in common with an iBook than a PowerBook. 15" and 17" PowerBooks can take two gigabytes of RAM because both RAM slots are exposed to the user. iBooks and 12" PowerBooks have only one RAM slot. The additional RAM is soldered onto the logic board and cannot be removed. Your 1.25 GB of RAM is going to be the most RAM you can have in your 12" PowerBook. means iBooks can take up to 1.5GB of RAM.

In a strange twist that further complicates the 12" PowerBooks RAM limitations, iBooks have 512 MB of RAM soldered onto the logic board. That means iBooks can take up to 1.5GB of RAM.

Sorry for the bad news but at least you know why you could not find the second RAM slot.
