Running Windows 7 Professional, I upgraded to 8 GB (2 X 4 GB cards). In Computer-Properties, system now says: "Memory - 8.00 GB (2 GB usable). How do I get it to use the additional memory it recognizes is there? Thank you.

You're very welcome.
Yes, that processor can run a 32 or 64 bit OS.
If you don't have a W7 64 bit installation disk (recovery disk set), you can contact HP and order one for around $10 delivered. 1-800-334-5144 in the USA/Canada.
Have the serial number handy to give to the customer services rep.
You will need to clean install W7.
You cannot upgrade from a 32 to a 64 bit OS, so you will need to reinstall all programs, personal files, etc.

Hi:
You would have to install a 64 bit operating system.
The most memory a 32 bit operating system can see and use is 4 GB.
Why it is only seeing 2 of 4 GB, that I would not know.
Normally you should be seeing 3 of 4 GB.

Anytime.
Glad to have been of assistance.
Here is the Intel spec sheet on the processor your notebook has.
http://ark.intel.com/products/36695/Intel-Core2-Duo-Processor-SU9300-3M-Cache-1_20-GHz-800-MHz-FSB
Under the instruction set spec, it indicates that it is a 64 bit capable processor.
