Hi there,

I am having a strange problem with one of our Lombard Powerbooks: It freezes completely from time to time. No spinning beachball, nothing. The picture remains on the screen, the mouse does not move and the keyboard does not work. No remote logging in either. The system is gone. This happens randomly every once in a while, but easily twice or thrice on a work day.

The problem only exists in Mac OS X, and has existed ever since 10.0. With each OS upgrade my hopes went up that it would resolve the problem, but it still persists. It's not the RAM (384MB), I have already exchanged that with memory from the other PBs. Those have been running rock solid all the time.

Has anyone come across this particular problem? Or does anyone have an idea what could be the culprit? Do you think it's a software or hardware related issue?

Any help/support/ideas is/are greatly appreciated!

JJ.

I've never heard of anything like that, and it sounds very unlike OS X behavior. That makes me suspect hardware.

It actually sounds a little like the (tiny) hesitation when the HD wakes from being spun down. So perhaps the HD is a possible culprit. Can you boot an external drive and work that way for a day or two to test? Or swap drives with a similar Lombard?

Nope, that's not it. Apart from that the harddrive was upgraded a while ago (to a very (!) nice IBM 20Gig/5.400rpm/8MB cache drive) and that did not change anything...

Although this probably won't help you, I experience a similar issue on a Sawtooth G4. It doesn't happen as frequently for me (only about once a week), but it is annoying!

I do suspect it has something to do with waking up from sleep (hard drive?), but I haven't done too much research into it. When my machine freezes that way, it does not leave any sort of a crash log, which makes it really difficult to debug!
