Making Sure Your Computer Recognizes the New Memory

After installing additional memory in your PowerBook, check whether the computer recognizes the new memory. Do the following:

1Start up your computer.

2When you see the Mac OS desktop, choose About This Computer from the Apple (K) menu. A window shows the total amount of memory in the computer.

Total memory installed in your PowerBook

The total includes the amount of memory that originally came with the computer plus the new memory you added. For a more detailed breakdown of the amount of memory installed in your computer, choose Apple System Proﬁler from the Apple (K) menu.

If the memory is not recognized or your computer does not start up correctly, shut down your PowerBook and check the instructions again to make sure that the memory you installed is compatible with this PowerBook and that it is installed correctly. If you are still having problems, remove the memory and consult the service and support information that came with your computer for instructions on how to contact Apple for service.
