Macbook Pro Shut Down Problem!

Here's the problem. My 3 month old macbook pro shuts down "randomly". If I plug in the AC power, unplug it, then plug it back in, it will sometimes shut down. Also if I plug in my USB hard drive while plugged in to the AC power it will sometimes shut off. and If i unplug it from the ac power it will sometimes shut down. What the heck is up? logic board?

Here is what I've done:
Repaired permissions(nothing)
Ran a hardware check(fine)
I keep finding this code in the console- kernel previous shutdown cause: 3
or kernel previous shutdown cause: 5
(I had paralles installed, but I deleted it)

any help would be great

macbook pro, Mac OS X (10.5.2)

Welcome to Apple Discussions!

Since you're under warranty, you might just want to call Apple about this. If your Mac is shutting down randomly, then it might be hard to troubleshoot. You should back up your data if you can.

You could try a couple of things. You could go to Disk Utility and verify and repair if possible both permissions and the disk. And you could also try reinstalling the OS, just in case software corruption is a factor. But all this sounds pretty weird, and it will probably be quickest in the long run to just let Apple sort it out.

Good luck!

Welcome to Apple Discussions!

You could try resetting the SMC:

But I'm not really sure what's going on here. If resetting the SMC doesn't fix the problem, then it might be worth posting a new topic so that it will get more attention than one buried in someone else's thread.

Good luck!
