I have downloaded this widget that tells me how much memory i'm currently using. There's only 150 MB left of free ram. How do I decrease that number so my Powerbook will run faster?

Powerbook G4, Mac OS X (10.5.8)

    Have you installed the maximum amount of RAM possible? That would be 1.25 GB in many models. OWC is a great place to get RAM, and you can look up your Mac and see what the maximum RAM would be for your model.

    Good luck!

    Maximizing the installed RAM in any Powerbook, especially a 12" PB, is a fine idea, and I second S.U.'s recommendation. But don't be too concerned when you see only a small amount of free RAM, if there is also a fair amount of inactive RAM. The latter is just as available to applications that request it as free RAM is, and OS X is amazingly good at memory management. With Leopard running on a 12" PB you are always apt to be somewhat cramped for RAM, even with the maximum amount installed. With that combination of OS and hardware, you may just need to be careful at all times about how many applications you keep running at once. Quit the ones that you aren't actively using to make RAM available to the ones you are.

    One more thought here. When you look at the activity monitor check the Pages in and Pages out. That will tell you whether the computer is depending too heavily on the HDD for swap files. Your Pages in should be more than your Pages out. If not, you definitely need more RAM.

    Also, how full is your HDD? What is the size of your HDD and how much of it is available capacity (free space)?
