When I have the computer on (HP Laptop 4GB of RAM), with Open Office and mail, I am using around 1.75GB to 1.90GB of RAM. With those programs and 1 CAD program running like I usually do, the RAM goes up to around 2.35 normally.
Earlier, I had a lot to do and had 4 or 5 CAD programs running so I wouldnt have to close any out and I could keep working faster. With all those programs the RAM went to 3.60GM of RAM, which is what I expected.
When I was done and closed all those programs out, the RAM went down to 0.99 to 1.05GB of RAM.
My question is why after closing all those programs, did the RAM go so low, when normally when I close out the 1 program, it goes to what it normally is. 1.75GB of RAM?
