Why do I get "you must shut down your computer now" mssg?
Sometimes the cursor freezes before the mssg pops up. Sometimes not. My mac neighbour says it's not my HD and he fixed a directory problem I had. He tried replacing the RAM with a 512 but the problem did not stop, so we replaced it with the original 256. I always keep it pluged in. It's 5 yrs old. Unplugged, the batt only lasts 1 hr. My neighbour says it's old for a laptop, time to replace it! But I love this little guy.
