I thought I would share my success story. My wife has been having problems with her dual USB iBook for close to a year. It wouldn't sleep when she closed the lid. The only way to get it to sleep was to manually put it to sleep through the power button or apple menu command. I've posted this problem to various lists and tried a bunch of things like resetting power manager and running disk utilities. Then a couple of weeks ago she started having crashes. And finally the trackpad started malfunctioning. You could move the pointer, but you couldn't click on anything. Otherwise the keyboard worked fine so you could use keyboard workarounds, but life is a pain in the butt without a mouse. I tried logging in to another user and then the pointer was stuck dragging whatever it was positioned over. If it was over a window you would drag that window around when you fingered the trackpad, but couldn't release or click on anything else. Again I tried a bunch of troubleshooting things with no success. We were on the verge of buying a new computer (or at least buying an external mouse), when I decided to remove the 3rd party ram card I had installed years ago when she bought the computer. Bingo. All problems solved. We threw out the 128mb card and put in a 512 card. Now things are a lot faster (Tiger) and the iBook even sleeps, something it hasn't done in over a year. I still think she needs a new computer, but at least now she has a *choice*. I know checking for bad ram is standard troubleshooting procedure. I even had problems with my Pismo years ago that were a result of bad ram. I don't know why I didn't think of it sooner. Jim
