Hi,
I have MBP that will be 5 yrs old next month.
I have OSX 10.7.1 with 2 GB RAM.
Runs very slowly. More Ram has been recommended
How do I know how much I can add.
Thx.
Frank
 
You can find specs on all Apple products:
  • By visiting EveryMac.com
  • By using Mactracker
  • By entering your serial number here to find specs for your model. (Be aware that some models can use more RAM than Apple shows. Check EveryMac or MacTracker to verify.)
 
It is probably a good idea to stick to Snow Leopard on such an old Notebook.
 
Thanks. Found this for an answer:

The net result is that at least 3 GB of RAM should be fully accessible, while when 4 GB of RAM installed, ~700 MB of of the RAM is overlapping critical system functions, making it non-addressable by the system.
Ultimately, 4 GB of RAM may be installed, but not all RAM in excess of 3 GB can be used due to the possibility of memory "overlap".

Thanks again for your help.

Frank
